Yahoo Answers dominates its category, but there are a lot of complaints about spam and other useless content. Yahoo made a simple change to the product today that could help fight that spam. Users can now track others who tend to provide excellent answers.
This won’t reduce the amount of spam on the site, but it will help highlight the better content and allow users to create social networks within Answers. To use this, users simply mouse over the avatar of a user they like and click “Add to My Contact.” Recent content from contacts appears in a user’s home page and profile page.
This won’t directly help users who are searching for content or asking questions, but it will certainly bring better content to the foot of users who simply browse the site.
