Taking a poll on an unconstitutional or inappropriate question would be silly, if the question clearly falls into one of these categories. Otherwise, since no lives are at stake, a popular vote doesn't really seem all that dangerous.
NAME and RANK
No one could possibly be suggesting that the XP system is some kind of direct measure of the value of a post (or poster). XP should have some connection to the time and/or effort spent here but that obviously can't translate to "worthiness" in any sense. Obviously, any "newbie" might actually be an experienced Perl programmer or expert in some other field. XP can only provide a hint to the background of an op and providing it up front can either be seen as a convenience or as a distraction -- not some sort of human right's issue.
