If I understand you correctly, that lack of interaction bothers me too. Aren't social networks supposed to be made to socialize? I tried every method I could think of to get that interaction, but most of the people don't reply to most of the messages.

I don't know if it could be because of the number of inactive pump.io accounts which leads to less users, because I post about topics people aren't interested about (I try to vary such topics, although I post mostly about anti capitalism), or maybe there are other reasons I didn't think about.

I just keep posting in pump.io because of Dianara. If I had to use web interface (hadn't use it for a long time) I would probably switch to another network or would just quit posting.
