I’m debating signing up with Facebook. And I would like to ask the Internet at Large — is it worth it?

I’ve spent time this week expanding my LinkedIn account — even though I haven’t actually used it before now, but people tell me it’s a great netowrking tool for finding a job.

And I read a newsletter about a guy who, when he looks for business interactive writers, he looks to see if they’re on all these different places.

But… are they really worth it? Especially FaceBook. Do they work in creating fan base and such?

I have a MySpace page — haven’t been to it in months. I don’t have a clue about “DIGG” (and would love to have someone explain THAT to me).

PLEASE??? Please, please? Discuss among yourselves…
