It's no secret that Yahoo Answers has been a big success for the company - it's seeing tremendous growth and being integrated into a range other services, including Yahoo Food. They're claiming 60 million users around the world, and it's undoubtedly the largest Q&A site on the web. That's surprising, because normally they're forced to acquire successful startups - in this instance, the success was homegrown.
Today Yahoo is announcing a partnership between Yahoo Answers and Answers.com, which provides encyclopedias, dictionaries, thesauruses, information from Wikipedia and more. As part of the deal, you can see relevant questions and answers from Yahoo when you're viewing certain topics on Answers.com, or click through to ask a question over on Yahoo Answers. Answers.com already have a service in this space - Blufr is a fun widget that you can post to your blog, but they're now also targeting MySpace users (hi5, Piczo, Friendster, Xanga and others are also supported). In particular, they've launched a contest to promote their embeddable "bluf-o-grams" - the prize is a makeover of your blog or social networking page. However, Blufr doesn't compete directly with Yahoo Answers - it's more about creating fun quizzes to share on social networks.
