I was going to open this for discussion on the Giants/Diamondbacks game, but the executives of SportsBlogs Nation have mandated that all of the Gameday Open Threads on the network discuss the Yankees/Red Sox game.
SportsBlogs Nation has a pay service -- only $15 per month -- that will allow you to chat about whatever team you'd like.* So that's definitely something to consider.
*If you live within 300 miles of the team you'd like to discuss in an Open Thread, this offer does not apply. Don't be ridiculous.
