When I was young and I found this site, I thought it was the best thing in the world. In my head, I could throw out every other site because all the links are here first! Then I saw the comments, and it's very easy to feel like you're being informed on a topic when you see it has X upvotes (if it's this upvoted, it MUST be true!) when in reality, you have no position to judge the quality of a post because you don't know enough about the topic in the first place.

Now picture that, and then picture 1000 other people just like that upvoting a post, and the cycle repeats itself with every link on and on and on and on.
