@takeshitakenji Moreover, there's no way to say this without it coming across as vain, but if you make a positive social media place for people, they're more than happy to contribute to developing the social network, be it by developing code as you or @normandy or @bob or @moonman have for postActiv, or by testing the software and giving bug reports, or by bringing people into the network, or any combination thereof.  If you make a positive environment, people want to stick around.  But there's much more to that than just "being nice" - and indeed sometimes you have to be able to tell people "no".  And some people can't do that.
