Now Twitter is going down with their changes to the API rules we got a new alternative called App.net but sinces you'll have to pay for I don't think it will get the same result as we have with Twitter nowadays.
My idea is to create a new concept, based on the idea that a robust API is the basic to attract people and developers.
The project should be opensource so the geeks would have their chance to make the diffrence and make it a better service.
Even the non geek users can make their contribution, they can make feature requests.
Sinces I'm not fond of advertising I'm looking for another way to gain money to maintain the system. So I still got to think about this factor.
So currently I'm looking for peopla who want to join the proces of creating a beta version.
Most important: developer, designer.
