This via Steve Rubel; the University of New South Wales in Sydney, Australia is implementing a research project named CollaborativeRank, which they are calling a "del.icio.us search engine." Well, as we're all about search engines here at websearch.about.com, let's check it out.

The blurb on the front page states:

"Users on del.icio.us who give meaningful tags to helpful/timely URLs (as evidenced by others subsequently doing the same) will be rewarded with higher CollaborativeRank, which means that their tagging will have greater influence on this search engine's rankings."

So, according to the ranking system on CollaborativeRank, these are the top 500 taggers. Also shows their "areas of expertise", or what they tag most frequently in del.icio.us.

I typed in the search query "blog", and got back a list of search results. Can't quite tell if these results are from del.icio.us as a whole, or just from the top taggers, but either way it's a nice search tool.
