Want to do some keyword research? Check out this cool tool that Cre8asite Forums member eKstreme found: Search Radar and take a look at it in action:
The tool looks like it pulls a variety of resources, so there may not be good results, for, say, search engine optimization. As iamlost points out, of the 4 main results there, only two (Bruce Clay and SEOBook) actually knew how to define SEO. But you can't count that as a real fault for Search Radar; it's what they're querying from the internet and the error of other firms that define SEO as "cultivating professional relationships especially with small to medium businesses." (Say what?!)
