Great concept, but many buttons don't have any label or tooltip, please add at least one of the two. The "hot" button is very cryptic to me. On my computer, i don't have an easy way to scroll left and right, so the layout is suboptimal. Clicking on the link once to show the comments and a second time to follow the link is not ideal. It should at least be made clear what will happen when you click. Maybe make the title black when it's just a comment toggle, and then blue when it will link to the article
