1. List the social networking sites you have either tried or still use.
MyBlogLog, Blog Catalog, FriendFeed, Digg, Blog Explosion, Google Friend Connect.
2. Of the social networking sites you’ve actually tried, which one is your favorite?
Probably MyBlogLog. Most of my traffic on "Hypatia's Hoard of Reviews" comes from there.
3. What’s the biggest drawback to such sites, in your opinion?
The time investment. GIGO: If you don't spend time building up a bunch of connections, they do you very little good. I try to spend a little time frequently, and not get too lost in them. I have several hundred contacts on MyBlogLog because I often check the 6 "people who have recently joined communities I belong to" lineup. If their profile indicates that we have common interests, I add them, and maybe send a message.
4. Other than it being the “hip thing to do,” what’s the main reason you’d at least consider joining such a site?
It boosts my audience and makes it easier for people to find my writing.
