I don't know why everyone's so anti-facebook. I think it's great, if for no other reason than it's incredible popularity. I'm sure there's a billion websites just like it, but what's great about facebook is that so many people have one, so you can keep in touch with (almost literally) everyone. And that's the same reason it is a great marketing tool. There are millions of active users that could potentially become your "fan". And it's flipping FREE!
Of
course you should make one.
Everyone's reasons not to are the same reasons I say you shouldn't do reviews though, so I guess I see where they're coming from. But it's really not that much work... especially since you have your brother doing it now! lol
