In the comments for articles, if you click on the upvote/downvote area, it creates a sort of 'popup' page that has who upvotes and downvotes. Problem is, if you click on a comment near the bottom of the page (or anywhere away from the top of the comments page that doesn't happen to have any real reactions yet), all you see is the whole site darken up with no indication on what happened. You need to scroll all the way to the top of the comments section of the article in order to see anything. I think if this is to stick around, it would be better implemented by having the info as a 'mouse-over' feature.
Plus, honestly, not a fan of seeing how individual people vote on comments. I mean, yeah, it'd be funny to point out certain trolls who just go through and downvote every comment in a particular thread, but I can see this as a way for users to openly 'bully' people by making it KNOWN they downvote specific users. It kind of gives them "the power" and potential reaction that they want.
