[I know another item about Google's dictionary was posted already, but I wanted to add this bit with a different focus]

Answers.com has lost what might have been a significant source of traffic since 2005: the top-right definition link from Google results. Google now changed that link to point to a dictionary hosted on their own servers. For users, the new definition page will be more uncluttered: no big navigation, shopping products, or advertisements (yet). Google's dictionary page also looks like it misses a thing or two from the Answers.com page that might be relevant, though I'm not sure how many people were looking for extensive background information on a word in the first place (?).

Before Answers.com, Dictionary.com had suffered the fate of being dumped by Google.
