I was reading an article about the AnonOps IRC server being shut down, and started wondering if it would be feasible to use the same sort of concept used for bitcoins to decentralise communication like a forum.
That doesn't make sense, bitcoins relies on insufficient processing power with cryptography to generate bitcoins.<p>You could just set up your own IRC server.<p>Or if you want to go fancy (locally): <a href="http://wiki.daviddarts.com/PirateBox_DIY" rel="nofollow">http://wiki.daviddarts.com/PirateBox_DIY</a>
Look into Usenet for a forum with no central control (it's pretty much peer-to-peer, but the "peers" are servers, not any random guy); I have no idea what Bitcoin has to do with anything, though.
bitcoins should be used for karma.... e.g. you calculate the real time a user spends on the site, a function of the amount of time typing answers and the upvotes they get, and this results in bitcoin karma.
