Hot technologies for 'Search 2.0'

Confused about the direction of search technology? We certainly are. That's why we were particularly interested in this primer on "Search 2.0 vs. Traditional Search."

A lot of blogs and sites write about this important area of development, often in generalized or densely technical terms. But Read/WriteWeb, a part of the Web 2.0 Workgroup blog network, helps explain the status of search technology the best kind of learning tool: examples.

Specifically, the blog summarizes five hot technologies that are on the front lines of search development--Swicki, Rollyo, Clusty, Wink and Lexxe. (Is it just me, or does this sound like a roster of cartoon characters?) Key features among many of these emerging technologies, not surprisingly, are community and collaboration.

None of these is a household name yet, but neither was Google only a few years ago. That could change quickly and drastically in the Web 2.0 era.
