Since I've been around both sites almost since they began, I'll toss in some thoughts.
First, welcome to CD!
Second, the personality of the two sites is very different. Sometimes I'm more in the mood for one, sometimes the other. BX tends toward being a bit too pro-establishment...even when the establishment is full of beans. They insist on seeing clothes on a naked emperor. They are also easily offended; must be nice to be able to run a business while being that thin-skinned. I can't get away with that in my business. This site, by contrast, has more people who sometimes shoot from the hip and have no personal filter, particularly when it comes to the names of a few past coaches & AD's. And, just being frank, a few of the folks at this site are pretty vindictive in terms of their emotional disappointment at the failures of previous athletic program luminaries.
All the above can be taken with a grain of salt.
I have two primary gripes, one with each site. My BX gripe is their institutional assumption of superiority, occasionally straying into out and out arrogance. My gripe with this site is the tendency of some posters to immediately start calling other posters names in a knee-jerk way that makes them look like a 5th grade kid on a playground.
CD, I found your posts on the other site to be pretty adult, and will miss your presence. Good luck over here!
