How would making the site pay-to-view only do any good? If people wanted to access it that badly, they'd just pay. All that is going to do is decrease the membership here and drive people away.
I think the key should be to be a little wiser about the information you make available. Seriously, these are things they teach and preach to middle school aged children. I agree this feels like a family of sorts, but bottom line is, it's still the INTERNET.
I just think in general sometimes we all really need to consider what information we so easily offer up without a second thought.
