43things (esp. along with other Robot Co-op sites) is a brilliant, innovative site. It’s beautifully designed and its simple and elegant philosophy for functionality demands attention because even now … after close to two years, I’m still discovering new ways to use the site. I can see the same elegance and philosophy in the Should-do form. It may be a while before a bunch of should-doers figure out how to use the site to it’s full potential … but I definitely see a winning pattern here. Best of luck guys! I can’t wait to see what else you come up with!
