When I think about it, downvoting seems like a counter-intuitive feature for Area 51--if people don't like a proposal, what gives them the ethos to counteract the interest of another person? Stack Overflow is made of many communities, and ideas that are just budding might be nipped in the bud because a small number of people don't like it.
Is it okay for one person's dislike in an interest to be a case for countering a like that shows the interest of another?
I do realize that the subscribing feature is what really causes a site to progress to the next level, but... does downvoting make sense? What is the context of downvoting on Area 51 when people from hypothetically opposite communities collide? Is it okay for opinions to cancel out if Area 51's nature is to not provide services to any one community, and instead, give various ideas a chance?
