It's only just being put together; the plan is to have a bunch of ways of voting on quotes (you can do that now), tagging and categorizing them, getting more that you'd like based on your past voting, competing to attribute them, etc etc.
There's also a Twitter that gets a quote pushed to it every so often:
It looks spammy at this writing, but that's just for testing; in normal operation it'll just get a quote a few times a day. So it's safe to follow. :)
Take a look, and tell those of your friends who are sufficiently insane!
