Pinterest is a new social bookmarking site where you can "pin" your interests and "re-pin" others' interests that you like. Right now it's in private beta, and I'm sure you've noticed some other bloggers out there that are already using it. But you can get on the list for an invite when they open!
It's a wonderful resource for saving your ideas for home, weddings, parties, style, fashion, and much more! Until it's live you can also follow boards here.
