Wow this round was a cinch.
Despite some of my comments there were some worthwhile sites. Box.net is better than similar sites I had used before, and I'm sure I'll find a use for EnCompassCulture sometime despite it's unweildy name.
My biggest complaint with some of the sites is the way they only provide a single search box. Sure, most people will only ever conduct basic searches but there are some of us who demand more!
