I used to work at Google.
I can personally vouch for the fact that not all gay employees joined the "Gayglers" (I did, but I know quite a few who didn't.) I don't see why "Greyglers" should be any different.
And for those of you making comments about how people over 40 are incapable of being creative or good programmers, I have to say that my experience speaks differently. Some of the best programmers I've ever met (and worked with) were the older ones. Then again, I've seen some superstar young programmers too, so I'm not ready to say that you have to be old to program well. That said, even many of the great young programmers I've worked with were less productive simply because they had to take time to learn how to work on a large project and maintain someone else's code.
