I signed up to App.Net; a $50/yr twitter clone that promises to respect developers and customers and not treat its users as eyeballs to be fed advertising. I get the impression that some of its early adopters have unrealistic expectations about what App.Net is and what it will become.
There is a sense among some early adopters that App.Net is a life-raft - an escape from the ghetto that Twitter has become. It's a paid service - that's all. I paid for a couple of years membership of Motley Fool 10 years ago - it wasn't rainbows and unicorns - just a useful forum that happened to be gated.
That $50 is a recurring fee so I'll see how things pan out this year. I've pledged my money but not my allegiance to App.Net . Right now though, it's interesting that enough people have put their money where their mouth is and signed up. In 2008 I would have paid for Twitter but they went a different way and continue to make bone-headed moves. I'm walter on App.net.
