Moneypants is a great site built around an online tool designed to help 20somethings manage their finances. I don't feel the need to (read: I am not organized enough to) have everything tracked like this but for a certain kind of person it could work great. Plus they have a lot of cool content on the site including interviews and True Confessions.
PS: As a commenter pointed out, the budget tracker on the site is a pay service, which makes it, hmm, a little less appealing to people who are watching their spending very carefully. But I still think it's a good place to look around.
