Umair at bubblespace draws attention to the success of MakeUpAlley. Here's a nice irony: a site about cosmetics that looks pretty scruffy but is hugely effective - because it provides a simple way for its participants to connect about something they're passionate about.

Umair sees big lessons here for VCs and geeks, and I see big lessons for marketing. What a stunning example of the declining value of pretty packaging and making yourself look good, in favour of helping your users look good.
