Web applications catalog

A company called Simple Spark has taken on the daunting task of cataloging web applications.  Have you ever used a search engine to look for an application?  You may just get a few in the first 2 or 3 pages of search results, plus you get a lot of other useless information you have to search through.  This site looks as though it will simplify that process and show you all the companies that offer products in your areas of interest.
