I'm a bit surprised that you published this to your bingo blog and not Kalzumeus.com. Aren't you worried about your stereotypical user clicking it by accident?
The only way in is via direct link to that URL. I put it there because I happened to have Rails code written to do most of the work here (back from when I implemented Like buttons for the site, prior to understanding what they actually do), and because I'm positive Nginx can take the load (it is 100% static content after the first access) but less than sanguine about my Apache setup.
