A Review of Iconfinder | Search through more than 114,000 icons by Jon Spooner

The illustration is GREAT. and the simplicity of the interface is nice. You've simplified it so much you might want to take advantage of it and add some more whitespace.

Also consider showing examples of search results for your E.g. Under "arrow, search or twitter" it might be nice to show the top 5 icons for each search term.

Great bit of intelligent marketing by posting it on this site! :) as most of this community is your core audience!
