We're rolling out new features to the site today called "Suggestions for You," These features help users discover relevant Twitter users to follow, based on social graph analytics and algorithms designed by our user relevance team. You can read more about this feature announcement in our blog post at http://blog.twitter.com/2010/07/discovering-who-to-follow.html
Twitter's vision for how and where these relevant recommendations will surface can be found on our website. With the API, developers can build similar features in their applications or, as we expect many of you will want to do, invent new utilizations for the data. Methods will be available for obtaining suggestions for the current user as well as getting the users recommended as similar to another user. Look for developer documentation on these new platform resources soon.
Finding relevant accounts to follow on Twitter is about to get easier. What will you build?
