I'm not suprised at the leap in accepted answer activity, I would be a pretty average forum user I join and participate but not too much, neither too little. Here is a short description of what went on in my head. I imagine it's fairly typical:
Suddenly I have my signature sporting 50% acceptance rate after some breif disorientation and indignation a check of the blog explains things. Although JA said anything over 50% was cool, I couldn't help but feel this wasn't good enough and clearly so did many others. Also I have only 12 questions and I certainly had more than 6 accepted answers so I was sure the calc was bogus too. The result being a high motivation to go and revisit some questions and accept answers. After calming down a little though I didn't want to skew things by accepting answers for accepting answers sake, but equally there was no way I was sticking with 50% !!
My questions with unaccepted answers were mostly because I either answered them myself or two items where no answer was really forthcoming. So the majority of cases was easy enough just accept my own answers. In the final two cases I created my own answer describing how I abandoned the problem or solved it some other way, or accepted the best of a bad lot, as I can always return and accept a different answer should it be forthcoming. But, truth be known I suspect these questions will languish in the darkest corners of the DB only to be seen by the occasionally challenged googling dev only to have it's tab closed immmediately when it's obvious there's no helpful solution. In the meantime technology will march on at the insane speed it does and the question becomes obsolete anyway and quietly dies unnoticed, no loss there then really.
So I now have 92% accept rate, much better, and I haven't left SO questions sporting bogus accepted answers.
