I disagree.

First of all, most people don't post at all.

Second, many who do post only occasionally anything that might give specific info. I mean, I can make posts like this all day, and what in the world do they reveal about who I am?

I have a hard time thinking back how many years it's been since I posted a specific flight I've been on. (And in any such rare case, I didn't post my seat number or anything.)

In the AA forum, when I tend to post stuff about flights, it's almost always general stuff, not stuff specific to one flight.

Not that I care that much if AA figures out who I am. I'm not posting any stuff about AA that I'd be scared if it was attributed to my real name. (Some other forums dealing with other travel companies, maybe .)
