I've been working on a secret project the last few months – SearchR.com, a roll-your-own, viral Browser Start Page with some social networking aspects and tagging for podcasts. According to BubblePrice.com, it's worth 300K already.
Actually, it's just a joke. Bubbleprice is another site mocking Web2.0. It isn't as funny as Isolatr, my favorite anti-web2.0 site, but you should still check it out for a good laugh.
