Yeah, it's pretty thin out there. I have an ongoing theory that a team's fan base is (gets) stupider the more success they have, so it's quite possible that the Yankees have the single dumbest collective fan base. The comments on almost any Yankee post on Twitter prove this nicely as does the entire nyyfans site.
The Bronx View: This is a good one I discovered recently, they run through every day's minor league games with extra insight, definitely recommended for anyone interested in closely following the NY minor leaguers. Rating: 9

Views from 314 Ft.: This is a very new site started by all of the non-Mike Axisa writers on RAB, they post a bunch of times per day but it is generally pretty superficial and often wrong. Hopefully it will get better, but I'm not holding my breath. Rating: 4 for now

Pinstripe Alley: I believe every team has a SB Nation site, this is NY's. Again, a lot of posts, so good for those constantly jonesing to read Yankees-related material, but again their pieces are often completely wrong, based on faulty theses and often just totally pointless. Rating: 5
