From Amir on Orkut:

CleverCS is a forum for clever computer science ideas, particularly in more applied areas. The emphasis is on ideas that most people would understand without much technical expertise in the area. The ideas may come from recent publications or may merely be speculative discussions on possibly interesting new research directions.
