Social network App.net is shutting down once and for all in March. The company said on March 14 it will be deleting all user data. The announcement comes two years after the company ceased active development on the platform. From the official blog post: Ultimately, we failed to overcome the chicken-and-egg issue between application developers and user adoption of those applications. We envisioned a pool of differentiated, fast-growing third-party applications would sustain the numbers needed to make the business work. Our initial developer adoption exceeded expectations, but that initial excitement didn't ultimately translate into a big enough pool of customers for those developers. This was a foreseeable risk, but one we felt was worth taking.
