I saw a guy at Hard Times recently that I've known for years, but we only run into each other every year or so. We talked about the az forum, and I asked him his forum name, and no way would he give it up.
Like he had something invested in keeping it a secret. That's fine, except it makes it easier to imply hostile things about someone when no one knows who you are. Like lobbing grenades from behind a wall, where no one can see you.
I know I keep harping on this point, but it wouldn't be such shark infested waters here if we knew who was posting. And, if someone really wants to know who you are, they'll find out. A little investigative work would be all it would entail.
I think it is all about the "hustle" in pool, and the excitement that comes with keeping a secret, and doing something that is "prohibitive". Kind of like ditching school.
I like it that some guys who may have more to lose, post their real names and even a photo, like Jay Helfert.
