Well Gurunet (GRU) hasn't been standing still with its cash and public currency.
This week two things happened that are really exciting.
Second, Search Engine Watch reported that Google is now using Answers.com as its dictionary service. If you type in Abraham Lincoln into Google, you'll see on the upper right of the return page a small link that says "definition". If you click on that, you go to Answers.com for a detailed description of Abraham Lincoln. Try it.
All of this bodes well for Gurunet as it moves from a niche service to a mass service.
