Music 2 Work 2

I have spent a good bit of time recently trying to "get friends." This seems a rather strange process to me. During my life I have just become friends with other individuals - for whatever reason friendships are just formed. So, to spend time on music websites, asking other musicians and artists to become a "friend" to Music 2 Work 2 feels a little odd. How important is it to have lots of "friends" on a website? Should I feel rejected if I never get a response from some people that I ask? I have to admit, it is a good feeling when someone I have asked to be our "friend," responds with a "yes" and a note of encouragement.
