I think I'm deciding that I don't get anything out of most of these social networks. They were nifty ideas at first... but with the number of them there are to manage, and the number of invitations, notices, alerts, applications, "pokes", etc., I just don't have the time to spend on something that ultimately provides me with no value.
If you want me to know how you are, IM me. txt me. email me. call me. see me. but you can no longer friendster me.
I predict the demise of my other profiles someday also....
