What is Mashable Follow? Well, Mashable had an extremely successful 2010, growing from 15 staff to 40 and increasing our output to more than 45 stories per day. We also launched new channels like Business & Marketing and Dev & Design.

The downside of all this new content: More content to sift through! How about we let readers log in to Mashable and only follow the topics that interest them?

That’s what Mashable Follow is all about: Log in to Mashable with your Twitter or Facebook account and get a customized stream of stories based on the topics you choose. The new “Follow” buttons on every story let you subscribe to those topics via your “My Stories” feed (and coming soon, email!).

To make sharing our stories even easier, Mashable Follow allows readers to add their Facebook, Twitter, Google Buzz and Digg accounts to their profile pages and share to all of these services in a single click.

We’re not done yet! Mashable Follow also lets you create a profile page on Mashable, promote all your social media accounts, and connect with other Mashable community members who share your interests.

One more thing: Badges. For a bit of fun, Mashable members can now receive virtual goodies for sharing stories, connecting with other Mashable users, commenting on articles, following topics and more.
