I like the concept & it sounds like something that could attract other closeted coaches & athletes. However, I'd hope that down the road people who blog @ your site are ultimately encouraged to live out their lives as true as possible versus encouraging them to stay in the closet forever. Just sayin...
Two things that stood out for me like a sore thumb:
QUOTE
I am a thirtysomething closeted high school basketball.
I believe a noun is missing @ the end.
QUOTE
I have dabbled in the gay world for a long time...
Dabbled? 
Ummm, I think I'd try to use some other verb or rewrite the sentence to express what it is you're trying to say. Remember, being gay isn't some sort of part-time hobby like say "I dabble in art." Again, just sayin...
