haha true, I think the thing I am most after with this experiment is a more collaborative "alive" feeling outside of social networks. but of course we don't want to grant everyone write access to every part of every page.
Unfortunately, if this succeeds, you'll need to figure out a way to prevent (or mitigate) spam and other abuse. It's an awful problem, and I'm not sure if there's any way to really deal with it. A PGP-style web-of-trust might work, but that has its own downsides.
