For me personally, when FB first came out, I had no interest in it. One of the college clubs I was in, I had to get FB to keep up with the events. Once I got used to it, I didn't mind it. I just didn't handle the "friends" thing very well at first. Eventually, I realized I could have a professional account and a personal account, and maybe even another account where I'm having fun, but not hurting anyone's emotions in the process as well.
FB was annoying at first, but it has been a great tool to help me seek out whose real and whose not. If certain people don't respond to me, and I see they have all the time in the world for other people all the time but never me, then I know that in a week or two or so, it's easier for me to "feel" things out and dump their @$$#$. I usually leave the door conditionally open by either using my professional account to add so and so back or, or letting them ask me to add me back on my personal profile if I think they care enough. Then if they are willing to add me back on of their own initiation and accord, then I know that they care enough to use the energy to do that. It's not the idea that it takes a lot of energy to add someone back on, because it doesn't. But it tests that person's "psyche" and true empathy for you. I don't use it as a weapon, only as a social tool when I really need to. It has helped me a lot in this respect.
