Facebook's Pages are way better than the Networked Blogs application we were using before (mostly because you don't have to add an application) so I've finally set one up. Become a fan of BtB on Facebook!
You can also follow the site on Twitter by following @BtB_Sky.
And if you're an "old-school" RSS type person, use this. Or go uber old-school and follow us via email -- if you're on the front page, fill in your address in the left sidebar just below the More SBN Blogs section and if you're on an article page, fill in your address in the right sidebar just below the RSS Subscribe section.
