Befor I left the #fscons for the day I jumped right in to the discussion on social networks between @sazius @mmn and @theru
It gave me some things to think about. For me some kind of central meetingpoint got lost when identi.ca became the most known instance of the new pump.io. There was a big splitupp I still feel. The biggest part joined sooner or later the fediverse of gnu social. But we are not fully satisfied there. The group-functions, once one of the strongest arguments for identi.ca don't work between different instances and as @mmn told will most likely never work. So you can just forget about it.
Pump.io seems to be some kind of useable when you use a great client like pumpa. But I still miss something like identicurse on the terminal. Not to talk about the webinterface.
Then you have friendica and diaspora: I tested those, did like them in some way but always left after a short time. More lazy than active. I just started identicurse, andstatus or mustard and met enough people to read and write toand just forgot about the other options.
It's like if the big island identi.ca that was a nice place long away from the dark continent twitter broke apart and now you have some atolls with nice little islands where people meet another and sometimes even look to the other atolls where you remember people are living you once knew. But only travelers like @sazius really take the advantage to visit all islands regularly.
I don't know the answer to the problem. I only can say I once knew which way I could show people planning to leave twitter, facebook and G+. Now I don't know any longer. I stay in some kind of habbit with gnu social, hoping for the best and somtimes I row over to this place.
Luckily I have a life AFK too.
Pump.io is a really great network if you give it a chance and invest some time and effort on it. Sadly many people doesn't do that.
Also sadly, many identi.ca users didn't give it a chance when identi.ca became part of this network.
As for the several incompatible "free networks".. that's what the W3C Social WG is trying to solve. But these things take a lot of time, a lot of work, and people willing to agree on things.
