Maybe put instructions on the actual button?

I reddit on a 27" monitor. The center of a reddit page and the sidebar are so far apart that it's natural to actually turn my head slightly to read a sidebar. Sidebars typically contain information like subreddit rules, that I'm only interested in if I want to post in that subreddit.

What I'm getting at is that the UX is rotten on a larger screen. There are no instructions on the button, and there was no stickied explanatory thread, so I pushed the button to try and find out what the entire thing was about. I got rewarded for trying to figure out what's going on by being not allowed to participate any more. It's more than a little off-putting.

A stickied thread titled 'You can only press the button once.' would be helpful.
