Just spotted this new project called Twister
http://twister.net.co/

Miguel forked Bitcoind in august, added libtorrent-raster to it for DHT and uses the blockchain to distribute microblogging but also private messages. Has a nifty html/jquery interface and even an Android app. All alpha.

Love it already :^) Finally something that fills the gap left by Witcoin and even better than I expected.

I'm setting up my home node now  :^P
