I'm totally going two Burning Man next year

Just got linked to this idea by Smigs - CAPTCHAs to stop idiots from even getting on The Internet in the first place - brilliant. The man's even referred to The Internet using caps, as should always be the case. They wouldn't even be able to look up the correct answer on Wikipedia first...

Kingdom Of Loathing - a hilarious, stimulating and generally brilliant online game (well, for the first month or so anyway) already implements a little feature like this, which I'd love to see embedded into IM clients worldwide. It's called the Altar Of Literacy, at which you must first prove yourself before being allowed into the in-game chat - it's even a bit harder than the above link, though, not too bad if you're not American or French.
