Google uses links between web pages as a sort of vote for a web page. So the more web pages that link to you, it's like more people are voting for your web page. But the cool part is that Google doesn't give each link an equal weight. If more websites vote for your website, your website must be good, therefore your links count more.
From a fairness stance it is not very democratic. Everyone does not have an equal vote. But in another sense it is democratic. If you are able to convince other people that your website is good, they will be more likely to link to your website, and this will increase your website's page rank, and therefore your voice.
I think it would be possible to create an algorithm that substitutes links for reasons to agree. Lets say you have an idea with reasons to agree and reasons to disagree. Each reason to agree would give points to the idea, and each reasons to disagree would take away points. But just like Google, each of these reasons could have different weight, based on how many reasons their are to agree with them. And each of these reasons could have a different weight based on the number of reasons to agree or disagree with them, and so on forever. Just like Google.
I think promoting good ideas is more important than promoting good websites.

I've been to your idea-stock-market website and am intrigued. You're
not merely voting 'for or against' an idea, you are actually
facilitating it's development -and thus creating the conditions for
evolution.
Recently I've been building an 'IdeaWiki' into my website and am
interested in having your assistance in implementing such an
evolutionary system. Here is the link:
