Normally, at the top of the page, there are links to the previous and next articles. For some reason, this isn't displaying for me. Any reason for this?

I am using Google Chrome, Version 26.0.1410.40 (current beta release) on Windows 8.

Edit: Fixed! Now, can we pretty please get the notifications implemented like you had in the hack-a-thon? That would be awesome!
