As for polls like this one, notice how small some of the suggestions are. While some of them are broad-range statements that Toady has already said a few things about, others are slightly more out-of-sight for the developer. While the constructions one could have been obvious, it takes specific goals to come up with the need for such a feature. Similar things may be said of levers and the like.
To cover security issues, Toady is justified in his suspicions. Smaller forums have less problems with said cheating, generally, but it depends on who exactly is paying attention to the thread. Note that before the forum switch, Toady didn't seem to pay any excessive attention to this thread at all. (I have sort of noticed a pattern... Unless there is something wrong with the way the thread handles something, he quietly takes it into consideration, no one the wiser. O.O) The more attention is given by the dev to a thread, the more it stands out, of course.
Just from what I have seen so far, the concerns are somewhat irrelevant, however, the reason larger boards have better registry protections and other protections against multi-accounting are for reasons quite like this one. Multi-accounting gives a single person slightly too much leverage. And in a case where there is a thread like this one, which is given somewhat heavy weight based on its density of information, accuracy of said information is fairly important. So measures taken to preserve this accuracy seem perfectly in line with me.
People underestimate the value of a quick, accurate, and fairly complete document presenting information to anyone developing something, no matter what said something or information is. This is the reason for Wikipedia's popularity. In any case, to wrap this up, the way this should be handled should be based upon the results we see, although adding something that indexed the users voting on a poll shouldn't be too hard. The system already handles whether a user has voted in a poll or not individually, so it is a matter of getting the system to output that information to the relevant user, namely Toady. More would be complicated and likely not worth it unless polls like this one are to become an ongoing feature.
