@Bruce @manton @cleverdevil Quite a few ADNers are over on pnut, an invite-only network that's a one-man show, albeit with a ever-growing API. Jamin Guy recoded Riposte to run as a pnut client. So I still get to use one of my favorite social network apps ever.
I'll ask Paul at Tapbots what he thinks about a Micro.blog client. May be an issue of what else is in their pipeline.
