The developers at SB Nation have been busy, and there's a few things I think should highlight for everyone.
The first is that a newsletter has been created to bring the most interesting stories from around the sports world to your e-mail box. You can just go to the main site, SBNation.com, to find more information on a horizontal info bar at the top of the page.
Another development is the addition of a "Like" Facebook button on player, team and event pages. SB Nation developer Trei said about it:
Facebook uses that information to update what sports teams and athletes interest a user has. That is cool, because if you have that information set in your profile and you give a website permission to use it, the interest can be used to create personalized experiences, including publishing relevant content to their news feed.
