It's SoutheastShootout.com, and to find out what it's all about, go here. CasonBlog also has a good synopsis/intro here. As he puts it:
Our sole goal - to build a big tent and generate buzz amongst the rabid and swelling ranks of fans in hockey's final frontier - The American Southeast.The site is in its infancy and will certainly be evolving, and all comments and criticisms of the site, the concept and anything else to do with it are encouraged (via comments there or here or directly in an email to me if you prefer).
As Caps fans, your participation will be critical in making "SeSo" work but more importantly in showing the rest of the hockey blogosphere how strong the Caps' fan base truly is. So check it out early and often, especially during intra-divisional games (where open threads will become smack-filled forums for real fans), and don't forget about The Rink - I'll still be here, and with this shot in the arm, I'm diggin' it all even more.
