Honestly, not a new concept, but an effective implementation non the less. I remember a few students at my old school creating sites that would be picked up on the schools filter (which would look for words like porn/games/curse words) and link a lot of the schools resources. The IT department being rather inept, saw the school website being blocked, and took down the filter until they could find out why.
