I also created and maintain granary, a library and REST API that reads, writes, and converts between silo APIs, ActivityStreams, microformats2, Atom, and other formats. It's used in Woodwind, Shrewdness, facebook-atom, twitter-atom, and instagram-atom, among others.
My web site is snarfed.org. It's WordPress with IndieWeb plugins and minor tweaks. I POSSE posts manually, I use ownyourresponses and ownyourcheckin to automatically PESOS likes, comments, retweets, RSVPs, and checkins, and I use Bridgy to backfeed silo responses.
