Knowing how much I love online networking, my husband is encouraging me to try "Second Life." I believe he's curious but leery of trying it himself. He just came back from a conference in which a Unitarian Universalist minister was raving about the virtual UU congregation she'd created in this virtual world.
I went to the site, but it looked daunting. More than that, it looked as though it could become a terrific waste of time and dangerously addictive. Supposedly you can promote your real-life products there - has anyone tried it for books? I should think the two would be mutually exclusive in that anyone who has time for Second Life probably doesn't have time to read.
