What if someone I know finds about this place and reads my posts?

One of the joys of posting your questions to an almost-omniscient Wall is that you remain anonymous. Even if you were to post your name, I would redact it (that’s policy.) Not to say someone couldn’t read a post and think, hmmmm, that sounds just like Cousin Louie, but they’d only be guessing. The more personal info you divulge, the more likely someone is to think they recognize you, so I think you’re safe, but you could always put in a few false leads to throw readers off!
