MetaStartups. The first word that comes to mind. Really. Why bother applying to Y Combinator and go through all the mess of first months of the startup building process, if you just pick a bright idea, click a few buttons, and here you go -- soon you've got a working platform gathering hundreds of thousands of users? At the end you could just easily migrate with all your audience to your own domain, and tadaaaam... Sequoia Capital guys, where are you? And what about Facebook itself? Why not provide a toolkit for startup builders? Like, you know, Google with all its cloud computing and tools for site owners, but only in this case for startupers. Inhouse startups. What could it be? So, you've got a platfor, with hosting, audience, tools for advertising. Actually, if only Facebook provided an opportunity to do server-side programming, so that a group (or whatever else it would be called) could deliver web services, not via this clumsy embedded applications, but directly, and also an opportunity to do your own advertising (of course, some share will go to Facebook), here you're done!
