Nice concept, unfortunately you get some strange results if you apply it to the new page (where I think it would have a much better use): http://i.imgur.com/afSPm.jpg

Is there a reason it seems to highlight at random?

It seems it pulls data from the HN homepage no matter what, so it's not analysing the contents of your current page. It then decides on the heat locations based on that data.

Script is here (hope that's OK to link to!):

there is a reason but it's rather incompleteness than an actual bug. the current version of the script only visualizes the posts of the front page.
