>I wonder how many never come back? I know there are *many* visitors every day who do not post, but are here to look, lurk and learn. That was my approach for about a year before I ever posted a message.

The majority apparently. I think about 1000 persons replied to the "How often do you log in" survey. I think that a fair estimate of the size of the active community. You might allow another 1000 (at most) for the regular lurkers who are too shy to reply to the survey.
