A profile on a site such as this, especially one without a picture or face, doesn't out someone.
Which just goes to show that there are different levels of "out".
Typically, people first come out to a friend or two, then perhaps a small circle of friends, closer or more understanding family members, etc.
I went that route a few decades ago. I laugh as I think back to my first visit to the local gay bar. First I was worried who might see me walking in, then I was worried about who might see me inside (this when the crowd was 95% gay).
But I never went back to tell people I knew before. Like classmates. A few weeks ago I took Matt to my high school reunion. So now I'm pretty much out there. Made it that much less awkward when I worked the OutLoud Chorus information table at the Art Fair last week. (Saw 3 people: a visiting professor from Greece, a client and someone from high school.)
Not that I talk openly in front of clients or some other circles (e.g. my straight football team), but if anyone looks they'll see a spectrum stripe on my car's bumper. And an HRC sticker on my suitcase (makes it much easier to spot on the conveyor belt).
