Yahoo Launches Contextual Search Tool, Y!Q
Yahoo has launched Y!Q, a contextual search tool.
It lets you "search for related information" on the content you are viewing.
The cool part of Y!Q is that you can embed Y!Q into your site by embedding tags.
The really cool part of Y!Q is that you can add a Y!Q plugin to Firefox (although the process needs to be simpler), and search any words that you highlight on any website!
Y!Q still in beta, but this service is the first strong challenge to my reigning search engine of choice in years.
