I just watched this last night; I thought it was exceptional. I think it is huge for Brian to feel comfortable with literally letting the world know, as there are risks associated with that; i.e. companies you ride for, etc. I liked how he was pretty open and didn't try to come out with this announcement, and then give a discrete explanation. On a side note, I though tit was pretty wild that at the age of 3, he claimed to have known something was different.
Lastly, I really liked 3D.
