Searching the Tagosphere

Have you tried the Wink.com beta? It’s here.
As their website says:
“Warning: This isn’t your Dad’s search engine… Wink lets you search across the Tagosphere. If you’re using del.icio.us, Digg, Slashdot, and/or Yahoo MyWeb, this is your search engine. Find the latest links that people like you think are great. Enjoy!”
It’s an interesting proof of concept for a search engine driven by social tagging.
If you need some help understanding tagging you can find a short explanation here at del.icio.us. I had one friend who called it amateur cataloguing and indexing! Anyway, it’s fast, cheap and works for some on the Flickr stuff.
