Tom Coates has been blogging and working on social software since well before either of them got that name. He cares very much about making the web a suitable place for people to live in, and has been doing so with Barbelith, UpMyStreet, BBC Radio, The Open Rights Group, Yahoo Brickhouse and FireEagle. He even started a blog about Tummeling called Everything in Moderation 8 years ago.
