So, can anybody elaborate on the history of and relationship between StatusNet, identi.ca, GNU social and pump.io? It seems like this fragmentation is another obstacle for success, besides the obvious issue of gaining traction.<p>And then there&#x27;s tent.io, which appears to be completely unrelated but have similar goals. Is there anyone with insights on usage numbers, development activity etc. of the different projects? In other words: What&#x27;s the best bet for federated, open source microblogging?
