It's a cool and easy answers index that allows Yahoo's users to post questions or answer them. You need to gather 250 points (answering questions rewards you with points) in order to be able to post links into your answers. My company have tried it and it works but only to an extent, it works better if you have good content and Yahoo users link to your site themselves. As a strategy I don't recommend it. But good luck anyways.
Yahoo Answers (YA) links are NoFollow so probably more valuable is traffic you might get to your site. A lot of pages in YA are indexed by Google so this is a good side of answering there. You have to get to certain level (number of points) before you can publish your link. You can also be easily banned, if you don't obey rules strictly.
yahoo answers is still one of the most useful internet places where you can have quality and professional answers and advices to all your questions... from real experts.
