Such meta threads tend to be rather blah. Also, when dealing with large internet audiences you eventually come to realize that everything is "commonly misunderstood", because no matter how often or how thoroughly you explain things, the vast majority of users don't see it, and the percentage that did see it shrinks over time as new users flow in. So the idea of explaining things to the bulk of the community is sort of a fantasy. The sum of all explanations has measure zero. I'm not happy about that but it is as it is.

I'm happy to answer questions and do it every day, but it's better to stick closer to where actual examples come up. What else do you still want to know?
