I have my own version of status.net, but mostly to log statuses from xymon/hobbit, rather than my own federated microblogging site. 

I already had twitter and I am ok using it, it's not that I do anything serious in it.  I did not know about quitter.se, I should look into it, thanks for the information.

In my opinion, I think that one of the problems is the change of infrastructure that was introduced with pump.io, that made many of the existing clients for identi.ca obsolete. Although some of these were flexible enough to be used in other status.net installations, some were hard coded to talk to identi.ca

This is changing slowly, but it will take a bit until clients adjust to the new API, until then, it'll be a matter of waiting for the adoption to occur.
