Another entry into search wars, Wink searches across people-generated tagosphere. Om Malik hits on some of the points I was talking about the other day, namely will users ever catch on to tagging in a major way? He says:

I think it needs a behavioral change on part of “searchers� who have become accustomed to simply typing their queries and then trying to figure out where to go. Sort of like bad cell phone coverage : we go used to it.

His other point about one major drawback with very accurate search, fewer page views & less advertising dollars, is a very important one.  I think Google recognizes this one too, hence the move to add more places where people are exposed to ads (gmail, gmaps, etc.)
