This topic would have been better suited for a blog; nonetheless, here's my input.
As someone pointed out once before, people love to jump in on the drama, or at least observe it. The less "exciting" topics just don't seem to generate much interest. I'll give what I hope is an innocuous example:
Comments abound on posts with titles that in any way convey frustration. Other topics, like the one wishing me a happy anniversary, not only get few views, but they get few responses.
Something my husband has reminded me in the times that I've gotten all amped up about hot topics in the forums is that when people communicate via the internet, they are not being completely genuine. That's because internet communication, as great as it is, is devoid of the benefit of body language, tone of voice, and truly personal interaction that is part of how we all relate to one another in the real (as opposed to virtual) world.
