Social software and simplicity

Great interview with Clay Shirky in the Wall Street Journal. Shirky makes a particularly interesting comment about social software:

It’s almost universally the case with social software that the software that launches with the fewest features is the stuff that takes off. The shift is from thinking about the computer as a box to thinking of the computer as a door, and nobody wants a door with 37 handles. Twitter has six features, and it launched with only one. A brutally simple mental model of the software that’s shared by all users turns out to be a better predictor of adoption and value than a completely crazy collection of features that ends up being slightly different for every user.

Empirically, Shirky seems to be right. Email, Facebook, Usenet, Twitter, wikis, Blogger, Flickr, Friendster, del.icio.us - all were incredibly simple when they launched. They certainly had a “brutally simple mental model of the software that’s shared by all users”.

But I’m not sure I believe this is true, and I certainly don’t know why it’s true, if it is.

Maybe a partial explanation is that having a simple shared mental model makes network effects much more powerful. When we think about social software as a user, we don’t just think about the software, we also think about the network of other users, and it’s important to be confident that we have a shared understanding with those other users. If we’re not confident of that shared understanding, we won’t connect, and the value of the software will diminish.

A search engine for open notebook science

There has been some great discussion in the comments on my post about “Open science”. One outcome is that Jean-Claude Bradley has created a search engine customized for open notebook science:

Request for comments on “The Future of Science”

I completed a first draft of my book “The Future of Science” last year. I was happy with much of it, but the draft was inadequate in important ways. I put it aside to let the ideas gestate. I took it up again a couple of months back and have since been hard at work on a second draft. This time around I’m much happier, and I’m now looking for a few people willing to comment on the second draft of chapter 1.

The book is aimed at a wide audience, and so I’m interested in feedback from a wide cross-section of people. I already know many people in the hard sciences, but there’s many other groups I’d also like to reach. For that reason I’m particularly interested in getting feedback from programmers, entrepeneurs, biologists, social scientists, students (both undergrad and grad), and from non-scientists.

If you’re in one or more of these groups, and interested in reading and providing comments, please let me know (mnielsen at perimeterinstitute dot ca). Of course, if you’re in the hard sciences and keen to read, I’d also like to hear from you! Unfortunately, this is not a paying gig, unless you count my thanks in the acknowledgements.

A few bits and pieces about what sorts of commentary would be especially helpful:

  • Which are the boring parts? Elmore Leonard has said the secret of good writing is to leave out the boring parts. Unfortunately, I find it hard to spot the boring parts in my own work, so comments from sympathetic and perceptive readers help. One trick I find useful is to score all my sentences or paragraphs: 1 = boring, 2 = okay, 3 = interesting. Eliminating, compressing or changing the 1’s and 2’s inevitably strengthens the piece.
  • Where is the book unclear? Where do I write like a specialist - a physicist, a geek, or an academic?
  • What important ideas are missing? Is anything flat-out wrong? What’s unconvincing?
  • How can I improve the impact of the writing? Simple comments - “this paragraph is flat”, “you could use a more active verb here” - can be incredibly helpful.

(You might ask why I don’t just blog the drafts. Certainly, this is becoming pretty common, and it’s something I’m keen to do. However, I’m yet to sign a contract with a publisher, and I’d like to get my future publisher’s endorsement before blogging huge swathes of the book.)

US Presidential Candidates on FriendFeed

All three of the remaining candidates have accounts on FriendFeed -Obama, Clinton, McCain. They’re an interesting contrast. Obama comes across as the most engaged, making effective use of things like twitter and Flickr. John McCain is making surprisingly aggressive use of YouTube, but otherwise is mostly quiet online.

Wiki set points

Imagine putting the Feynman Lectures on Physics up for public editing on a wiki (Feynmanpedia). Would they get better or worse?

My immediate gut instinct is “worse”. However, when I posed this question to a colleague I greatly respect he asked me pointedly if I’d actually tried it. It’s a good question. There’s no doubt that with some wiki communities, perhaps most, the Feynman Lectures would rapidly deteriorate in quality. But maybe with the right community they’d improve.

For many wiki communities there’s a useful notion of a “set point”, a quality level that an article written by that community will converge to over time. For a poorly written article, most edits will tend to improve the article, and only a few will make it worse; thus, the article will improve over time. However, for a superb article, many of the edits, even well-intended ones, will make the article worse, and so the article will get worse over time. The set point is the quality level at which edits improving and worsening the article balance each other out.

For Wikipedia the level of the set point is moderately high. I’m pretty sure that if one took a section out of the Feynman lectures and put it up on Wikipedia, it would get worse. On the other hand, if the community started with a blank page on physics, it’d demonstrably get a lot better.

For other wiki communities the set point is different. I’m a fan of the TV show Lost, and there is an amazing fan-created wiki about the show called Lostpedia. The set point of Lostpedia is quite a bit higher than the Wikipedia set point.

The idea of a wiki set point is obviously imprecise. Indeed, any idea that deals with quality judgements and community action necessarily will be. The caveats that need to be applied include: the set point will be different for different articles; even for a given article it will vary over time as contributors change; what does it mean to speak about the quality of an article, anyway; surely it makes more sense to talk about a set quality range, rather than a single point; and so on.

Despite these caveats, I think the set point is a useful way of thinking about wikis, and stimulates many useful questions. What types of wiki community or wiki design increase the set point? What types decrease it? How high can the set point go? How could we design the wiki software and community so that the set point is above the level achievable by any single human being?

How secure is quantum cryptography?

“Quantum cryptography not yet perfectly secure, researchers say” is the title of this piece in Australian IT News, based on a recent paper in IEEE Transactions on Information Theory. This old post seems quite relevant.

Open science

The invention of the scientific journal in the 17th and 18th centuries helped create an institution that incentivizes scientists to share their knowledge with the entire world. But scientific journals were a child of the paper-and-ink media of their time. Scientific papers represent only a tiny fraction of the useful knowledge that scientists have to share with the world:



Enabled by a new media form, the internet, the last few years have seen a modest expansion in the range of knowledge that can be published and recognized by the scientific community:



The most obvious examples of this expansion are things like video and data.

However, there are many other types of useful knowledge that scientists have, and could potentially share with the world. Examples include questions, ideas, leads, folklore knowledge, notebooks, opinions of other work, workflows, simple explanations of basic concepts, and so on.

Each of these types of knowledge can be the basis for new online tools that further expand the range of what can be published by scientists:



It’s fun to think about what tools would best serve the needs associated with each type of knowledge. This is already starting to happen with tools and ideas like open notebook science, the science exchange, SciRate, and the Open Wetware wiki.

Some people will object that this kind of expansion is not desirable, that the last thing scientists need is an expansion in the range of information they deal with. Surely we are already overburdened?

Underlying this apparent problem is an opportunity to develop tools to assist scientists in finding relevant information, and to ensure that what they publish — their questions, ideas, and so on — is seen by those people who will most benefit. Ideally, the result will be not only a great expansion in the range of what is published, but also a great improvement in the quality of information that we encounter.

(This is, incidentally, a good argument in favour of strong open access, namely, that building high-quality information-finding tools will require open access to the entire scientific literature. In a gated web, Google Search and similar tools could not function, for they rely on the collective intelligence of the entire community of people publishing on the web. By accepting closed journals, scientists are condemning themselves to relatively low-quality information management tools.)

There are, of course, major cultural barriers to acceptance of these new tools. At present, there are few incentives to make use of new ideas like open notebook science. Why blog your ideas online, when someone else could be working on a paper on the same subject? This isn’t speculation, it’s already happening, and sometimes the blog posts are better - but try telling that to a tenure review committee.

What this means is that in addition to building new tools for each of these kinds of knowledge, we also need to provide ways of incentivizing the use of those tools, so scientists are motivated to move information out of their heads and labs, and onto the network, where it can catalyse new tools and new discoveries. This means measuring the contributions made with those new tools, and working on legitimizing those measures within the scientific community. This will take time, but it can be done. Visionary computer scientist Danny Hillis has pointed out that problems which seem impossible over two years are often trivial over fifty - I suspect this is how we’ll look back at the current changes going on in how science is done.
