My Thoughts on Other Online Presences
GoodReads - this is my favorite online networking site because it's about books. It has real utility in my life. I don't have to "know" somebody personally to become their "friend" but I do have a criteria: the person has to be rating contemporary poetry (or books on Jungian topics). Cause I'm there to discover new books. On a daily basis I decline "friendships" with promotion-nut authors with thousands of "friends" and no poetry books in their library. I block the lecherous men with no poetry books and hundreds of "friendships" with ladies with pretty profile pics.
MySpace - No Tell Books has a presence on there and I check it about once a month. If you're a real human being, I'll probably accept your "friend" request, but it might sit there for a while before I get to it. I'm over the age of 15 so I can't go there too often, else I'll have a seizure.
FaceBook - It's the place for people who aren't interesting enough to blog to have a shallow online presence. On the plus side, it has an elegant interface. I appreciate that. I held out for a long time, but recently joined. I accept the majority of friend requests. One can never have too many pretend friends.
