Dude, you can't even downvote. You need 500 points, which, unless you're very smart or very lucky, doesn't come all that quickly. There are, as a rule,
far fewer downvotes than upvotes here, in comparison with Reddit, which means that there's less homogeneity of opinion: It's easier to voice contrarian or unpopular views -- and they're more frequently engaged with, rather than just hidden in a facile way.
Also the rules here are basically transparent.
On Reddit the downvote is far more powerful and frequently employed, and a lot of the rules are opaque/arbitrary. It's a terrible system for free discussion.
