Just to note, not every module that is not most often used is a bad one. I've use a dozen modules which are not mentioned, however they are all very useful in specific circumstances.

This also flows from the fact that there's not a single module that is 'universal' in it's aplication, or in other words not every thing could do everything! ;-).

On another note, I think it's fair to note that those who don't understand or use a module would most likely choose not to vote, since how can one vote without fully understanding the subject matter? On the other hand, those who do use the module (and, I concur, have fair understanding of it), would most likely vote in favor of it since it _did_ prove helpful to them in completing their job -- at the least, they've got something, right? As far as I'm concerned, I may not recall a single module that had I used at least once in one of my perl programs that I could vote down like that. Because, since I'd used the module, I'm in a way obligated (at least morally) to give credit where it's due. (the author for example). Secondly, if there was a module that I hadn't used due to lack of understanding, I'd simply pass it buy... and wouldn't be 'competent' enough to excercise a negative vote.
