I watched a webinar a couple weeks ago and in order to log in I had to use my facebook account. I know it is bad that I almost never use my facebook account but I mainly got it so I could have fan pages for a few of my sites.

I post comments on my fan page but almost never under my account name. What is going on now is that I am getting a lot of notes from facebook asking if I know all these people and I am guessing they are the other people who watched the webinar.

What I am wondering is since I don't really have very many facebook friends and never really use it to keep in touch with real friend or family should I friend all these people just so I have a base of friends that I can make posts for and try and sell stuff in the future.
