A few more that are new to me:
Away Team: The Year After Next Year - Dan, Abe and Noah are three Sox fans living in New York. Dan was at the same Sox/MFY game I was and also picked up on the anger (and that was a game the Yankees won).
Destination: Dynasty - By Zach.
3,079 Miles to Fenway, 3,448 miles to Yankee Stadium - Written by a Red Sox fan from Edinburgh, now living in Manhattan, and a Yankee fan from Portsmouth (UK)
Back to Foulke - Boston sports (from another guy in New York)
The Yankee Despiser (not actually a Sox blog, but one of the contributors is named Manny Ortiz)
