I am sure a few people on here might be memorable enough or give enough explicit detail to be known - but I really do believe most of us are just not all that unique and blend in. Read back a year or so - the same type issues, the same positions, and yet different posters. I do not believe the one I see could or would figure out it was me even if I told her my user name, put the site on her ipad, and pulled it up and pointed my posts out. And even if she did, I have said everything to her that I have said here anyway (not as in "I wrote x on a forum last night" but in a general what I tell the woman at the appointment every week sort of way)
