Restricting it might be useful as to not dilute his idea and make it unappealing to die-hard 'indie fashionistas'. Perhaps making his code generic, were this to ever be completed, would be useful in creating spin-offs.
well, i wasn't necessarily implying to have one site that dilutes the idea, but the solution for fashion could be cloned into another app for music, and so on.
the idea itself is reusable. suggestion engines could always use improvements.
Yea the real idea is to help people find hidden gems and from there find similar gems. The music scene is already pretty crazy though with last.fm and pandora and the millions of other sites trying to help people discover new music
