Not really, there is more of a "flavor" (even then I realize it's just a crack into the person, just like meeting someone at home, church, job, vacation and all that are likely to show different, even unrecognizable, differences, as will other factors, that is I realize whatever "flavor" I sense here may very well be different, even contrary to how I imagine them, if I met them in real life).
I have, rarely, dreamed of members I've interacted with on a board (I don't recall having any such dreams about any member here). In the rare case I was able to find out what the person actually looked like (which in one case included a real life meeting--and she was even more surprised by my appearance than I was by hers), it wasn't like in my dream (and if I dream of them again they'll probably still look as I dreamed of them before rather than how I now know they actually look).
Btw, I've tested online tests that claim they can figure out your demographic by a paragraph. I've used various samples, and I've never encountered one that was even half accurate, just based on stereotypes from what I imagine someone in the tech industry or more money than sense would come up with (in most cases I could even determine what was affecting the outcome of the test).
