Business Insider was on the scene to see what the coders were up to.
App.net isn't actually trying to kill off Twitter or Facebook, as some early coverage suggested. But it is trying to provide an alternative that lives alongside the social giants.
Last month, App.net unveiled a free, more limited version of the service, considerably expanding its reach; the hope is that paying customers will subsidize the free ones, while the free users make App.net more valuable.
The hackathon, App.net's second one ever, wasn't a huge startup jamboree, but the one-day event, held at the WeWork building on the border of San Francisco's SoMa and Financial District neighborhoods, drew a passionate crowd of coders, designers, and tinkerers. One developer, Jonathon Duerig, drove in from Salt Lake City.
Besides Caldwell himself, there were a few tech celebrities who showed up. One was Marc Andreessen of Andreessen Horowitz. (While Andreessen stepped down from Mixed Media Lab's board last year, Caldwell invited him to see if some of the independent developers had ideas he might want to back.) Another was Steve Streza, the lead developer of Pocket, an app for saving online articles for reading later.
The results are encouraging. As Streza subsequently noted, many of the new tools coming out of App.net look nothing like the ones we've seen built on top of Twitter's platform. The next target for the community: Providing a substitute for Google Reader, the news-reading tool that Google recently announced it planned to close in July.
That incident highlighted the need for something like App.net—a user-supported platform that won't fold up shop if it's not fitting into some big corporation's goals.
