"If you use a screen name here, type it in on Google and watch all your posts come up."

Oh no it doesn't. I just tried. Assuming "screen name" means the name we have at the top of our posts. (Of course if you click on your name at the head of a post all your previous posts come up, if you wait long enough. The recording angel never sleeps. Fair enough. )

(If you click on GUEST all the previous GUEST posts come up as well, and a skim through that explains a few things about attitudes towards those who choose not to use any pseudonym when they come in as a guest.)
