God the day I "need" or "want" a website for me to communicate with my "friends" is the day I stop using the computer. If you need to get a hold of me call me. No need for a dam website I have to log into to see what someone has written me. Only thing I see this stuff good for is underground bands getting known.
but i use it because you dont always want people to have your phone number or they dont want you to have theirs for whatever reason and there are times when you might need to communicate with them
