I won’t have any such problems just because I don’t have a FB page. I’ve already had a problem with one stalker and I don’t need another!
It’s a handy way to keep in touch with people. I work on a SF convention, honestly I have no idea how we organized and promoted the convention before FB. And I was even there, but I don’t know how we pulled it off. And given that we just sold out for the first time ever and the convention is still 5 months away, my disbelief is probably justified.
