FOOOD!
There's this site I found called We Gotta Eat. It's sort of like MySpace or Good Reads, but with a food focus- you save recipes, create shopping lists, create a friends-list and share with them. You can also choose to do things "private" and just use the database.
It's in Beta right now, so it's buggy, and sort of bare-bones functional (ex: friends have to be added manually.) But, I think if enough folks show interest, and the site gets lots of support, it could turn into a really cool thing. So sign up, help it develop and make friends.
My user name is Jess, if you want to have an immediate friend. =)
