I avoided Twitter for a long time, and Facebook for an even longer time, and eventually settled on using them in similar-but-different ways: * On both I only friend/follow people I actually know and like. I use both primarily to keep up with/talk to my actual friends. But it's a different circle of friends on each service. * Facebook is locked down (insofar as that's possible), and I keep that down to people I knew in my college days since that's where they all are. I have 26 Facebook friends, and I'm quite proud of that. * Twitter is my "public face". Mostly I'm following people who live here in town, plus some tech-industry friends scattered around the country. Pickiness about who those people are, though, has left me with a rather lopsided ratio (following about 90, and somehow followed by around 900). The biggest difference is that public/private distinction; if you try to send me something on Facebook (assuming it lets you), I'll just ignore it. On Twitter I do pay attention to mentions and @-replies, and often that's an easy way for people to ping me when needed. LinkedIn I still haven't made my mind up about, but probably because I'm not currently looking for a job.
