Flickr search tools

Mashable has an interesting post on Flickr search tools, i like the look of Compfight. It seems to pick up more matches than the Flickr internal search on anything, like... oh... "red head girl" (to pluck a random example out of mid-air.) The fact there are so many Flickr search tools maybe indicates that it is not just me who thinks Flickr's own search tool is rubbish.
