As much as the other guy is trying to bait, there is some truth to this exact point - it's not exactly stupid.
Problem with most developers is that they work in a vacuum of their own thoughts. That's a super bad thing because you need to actively confront your own stupidity and weird beliefs and trust me, most people just fail to do that.
It doesn't help that Vosmug is not exactly "open" to criticism (if I recall, he is outright hostile to anything, no matter if it is justified and constructive).
In short - it is always good to put some ideas to vote, if only to get some additional feedback and maybe even some more ideas. Putting all things to vote and turning your project into "Create Your Own Adventure" by popular vote - not so much (though I doubt anyone would have enough sanity points to go through with that kind of scheme for longer than a quarter
).
