Freak. I'm on Pinterest now, too. However, Pinterest is freaking awesome!!! It's basically a place where you can have virtual pinboards, and when you find something you love online, you pin it! People can follow you and see what you've pinned and vice versa. I've been on it for the past 2 days... very addicting.
So, Pinterest is an amazing tool and everyone should get an account! I know you'll love it!
