Facebook or MySpace?

On several listservs that I belong to, the hot topic now is marketing to teens and tweens via the Internet. Especially the use of social networks such as MySpace and Facebook.

What's your take? Do you have a MySpace page? Facebook? Do you use them to market or just to make friends in the hopes those friends will purchase your novel?

This summer, I finally hopped on the MySpace train and got a page. I've been on Facebook for much longer. A while ago, I created a MySpace page for my main character of Canterwood Crest and while I'm working on it now, I'm keeping the page private until next year.

I'm interested in hearing your take on online social networks!

**In other veeerrry unrelated news** Jamie Lynn Spears (yes, Brit's sis) is pregnant. She's sixteen. Sigh.
