I had to be dragged kicking and screaming, but I like it. I like "seeing" my friends every day. Most people don't have time to write/return emails. This way at least there's some regular contact, plus pictures and updates on life events, etc. I have mine pared way down as to who can see it and I relentlessly hide content I don't want and ignore overtures from people I don't know, so I feel it's easily manageable.
