So why not adapt the Twitter model to this? You can choose who to include in your Bogon-net, and maybe set different confidence requirements; e.g., "Show me only results that at least 50% of my Bogon-busters have rated, and only show me results that have a 75% approval rating."

The problems I already see are a) having to compute all those scores, and b) I'm unlikely to rate more than a handful of sites a day - I think Google tried that with their browser toolbar, too.
