With Facebook being that awful mess it is and always will be, Twitter becoming an awful mess, too, Google Plus being not really better than the previous two, App.net seems to be on the right track. A social network that is not basing its revenues on advertising but it’s selling subscriptions. Users pay $50 a year, get a service that seems not too different from Twitter but the product is not you. It reminds me of status.net and diaspora, it even supports PubSubHubbub but it’s not free-as-in-freedom software.
I support such experiments: selling advertising is not only boring but dangerous for the society as a whole. I’d rather pay to own my social graph (like I pay for this hosting+domain) than be sold.
