George, thanks for your thoughts. If all of OronD's thumbs up were tallied without the thumbs down, he would have over twenty thousand of them, at least, maybe more, and deserving of them all. I don't give out thumbs up or down very often, and I don't pay a lot of attention to them, though if they worked well I would probably take them more seriously. But the numbers are too easy to manipulate, which is why we see people with 10 answers and 600 thumbs up, and people with a thousand answers with hardly any thumbs up. Page through the highest ratings list and you will see what I mean.
I am more interested in the moderation aspect of the blogs, and the inability to get rid of bad/inappropriate/malicious answers. Yedda used to much better moderated with a staff that was proactive, looking out for problem posters. They (the staff) seem to be gone now, and all I want is the tools that they left behind to control the insanity. I know there are some staff left, and if you write them often enough eventually they do something to a specific post or poster, but that is a reactionary position, and not very timely. In my position, I have thousands of blogs I have posted answers on, and for me to write a letter to the staff every time some crazy follows my posts around and posts nonsense to try and drive me off would take a lot of writing and time.
Like you, some of my answers take a half hour or more to walk someone through a DIY problem. I only have so much time in a day to spend altruistically helping strangers, the same as everybody else. To spend time writing to the staff when I could just push the delete button means someone isn't getting an answer from me. Just trying to deal with pushing for a small change has cost me probably fifty answers to people who need some kind of help or attention that won't get it from me, and possibly from no one. There are thousands and thousands of unanswered questions here, and many of them were probably important to whoever asked.
I also answer a lot of medical questions, and getting the right answer is important, sometimes life or death. Obviously we can't be held responsible for someone not getting the help or advice they need, or not standing between them and a bad answer. But, as often as I insist that this is just fun, it is deadly serious at times. That is the most important reason for having moderators, because people can get hurt as a by product of knowledge or ignorance, and someone with common sense and a sense of calm needs to keep an eye on things 24/7.
