My post of 09:05:33 today should be withdrawn by now. I shall repost it here with alterations.
"I have been trying to find the GN membership stats, which we were told a couple of years ago. I can't find them, but I think that there were tens of thousands (80,000?) of members then.
Some posters reveal a lot about their present and past locations, their current political party membership and their past affiliations, and their occupations and interests, to say nothing of various bits of other personal and family stuff.
It is not just the limited number of active involved members who know all these details about frequent posters. All of those 80,000 already have access to that information and if they know someone in person or know of, say, a local party activist by repute, who features prominently on a much-followed topic they can identify him/her without difficulty, plus anyone who is NOT a member but has wandered onto the site because of an interest in some other topic can browse the forums and read all the posts.
GN putting things on FB and Twitter is a new dimension (and they have changed their policy on that) but GN has never been a closed site. That is why we are constantly reminded not to post info which could identify us. We can't have it both ways - if you "come out" and post private problems and opinions on a public site, you can't also stay behind a firewall. Even a section for members only would be open to the eyes of the tens of thousands of present and past members."
