Dave Winer, on App.net:

What seems very unlikely to me is that the new thing will fall neatly in place on one company’s servers, or even with one company’s servers at the center. It’s never been that way. Going back to the previous examples, C and Unix shipped in source and were widely adopted. After a short period every system had a C implementation, with a lot of interop. There were huge numbers of PC clone makers that all ran each others’ software. Anyone could start a web server.

It seems to me IoT people should pay careful attention to the current discussions around App.net. There could be a lot to be learned about platforms, interop and adoption.
