Here at SBNation, we're in the midst of some upgrades and re-designs of the individual sites.
But the behind-the-scenes folks have also just done a major re-design of the main SBNation home page, and have done an outstanding job...you can check it out here.
You can see the most recent posts for each of the different sports categories out there, along with getting a look at all the blogs within the SBNation family. And there is also a "featured posts" section, that highlights a few of the most interesting items out there in the SBNation blogosphere...
Definitely worth checking out...
