App.net is creating a platform connecting application developers with end-users, addressing a two-sided market opportunity that has been realized by the lack of engagement from Twitter and Facebook developers. To succeed in this market, three key criteria must be met: positive network effects, correct pricing and subsidizing, and avoiding winner-takes-all scenarios. App.net has identified its users as the subsidy side and developers as the money side, with a focus on quality over data monetization. The platform's success is not dependent on competing directly with Twitter, but rather on creating a unique experience that attracts passionate software users who are willing to pay for quality. With over 12,000 paying users, App.net has already taken significant strides forward and is poised to succeed alongside other platforms.
