@FrankLuke I thought you should post an answer too! If folks here did this more instead of debating in comments and down voting based on doctrine, it would be much more effective! Contribute well thought out answers to support one's case. Save reproof for lazy, sloppy, unsupported answers, rebuke for the uncooperative. It is always easier to tear down than to build! But it is easier to build than to clean up and re-build. undoubtedly the site would be healthier, more friendly and inviting!
@Dan SE sites really work best when they make expert-level answers accessible to the masses. You have that skill in spades, but if you are like me, it takes extra effort to answer that way.
@Dan I'm reminded of the mathematician whose research is only understood by one other person in the world: his arch-nemesis. ;-) The good news is that Calculus is now taught to teenagers. ;-)
@Dan yeah, I'm close to giving up on commenting on bad posts from either repeat offenders or newcomers who don't exhibit some clues. Which probably isn't good, but all I'm getting is grief for being "rude" if I try to correct people, so meh.
@Dan yeah, the whole thing with the accepted answer on brilliant's question that we were talking about earlier is one case of that. (That user, I mean, not just that post.)
