I teach at NYU’s Interactive Telecommunications Program (ITP), where the student population is about evenly divided between technologists who care about aesthetics and artists who aren’t afraid of machines, which makes it a pretty good place to see the future.
Part of the future I believe I’m seeing is a change in the software ecosystem which, for the moment, I’m calling situated software. This is software designed in and for a particular social situation or context. This way of making software is in contrast with what I’ll call the Web School (the paradigm I learned to program in), where scalability, generality, and completeness were the key virtues.
I see my students cheerfully ignoring Web School practices and yet making interesting work, a fact that has given me persistent cognitive dissonance for a year, so I want to describe the pattern here, even in its nascent stages, to see if other people are seeing the same thing elsewhere.
Users By The Dozens
We’ve always had a tension between enterprise design practices and a “small pieces, loosely joined” way of making software, to use David Weinberger’s felicitous phrase. The advantages to the latter are in part described in Worse is Better and The Cathedral and the Bazaar. Situated software is in the small pieces category, with the following additional characteristic — it is designed for use by a specific social group, rather than for a generic set of “users”.
The biggest difference this creates relative to classic web applications is that it becomes easy to build applications to be used by dozens of users, an absurd target population in current design practice. Making form-fit software for a small group of users has typically been the province of banks and research labs — because of the costs involved, Web School applications have concentrated on getting large-scale audiences. And by privileging the value that comes with scale, Web School applications put other kinds of value, particularly social value, out of reach.
We’ve been killing conversations about software with “That won’t scale” for so long we’ve forgotten that scaling problems aren’t inherently fatal. The N-squared problem is only a problem if N is large, and in social situations, N is usually not large. A reading group works better with 5 members than 15; a seminar works better with 15 than 25, much less 50, and so on.
This in turn gives software form-fit to a particular group a number of desirable characteristics — it’s cheaper and faster to build, has fewer issues of scalability, and likelier uptake by its target users. It also has several obvious downsides, including less likelihood of use outside its original environment, greater brittleness if it is later called on to handle larger groups, and a potentially shorter lifespan.
I see my students making some of these tradeoffs, though, because the kinds of scarcities the Web School was meant to address — the expense of adequate hardware, the rarity of programming talent, and the sparse distribution of potential users — are no longer the constraints they once were.
