At Jim's suggestion, I joined Facebook. Although their stuff loads faster because it doesn't have all the "bells and whistles" of some of the other sites, I don't find their links to perform certain actions to be very understandable.
I'm not crazy either about the network it automatically put me in since it picked one for me based on my location apparently. So I went back in and joined some other groups with people more in line with my interests. Joined the Ian Tyson fans group and the Acoustic Guitar Players group.
After I have a chance to cruise around the site a bit, I might change my opinion of it or be better able to understand it.
Just thought I'd comment.
