alt Hacker NewsIt's been a while I heard about X-Clacks-Overhead. I added it to my own page to commemorate everyone I lost along the way. After reworking my site from a custom blog engine to plain web, I forgot to re-add the custom headers. Thanks for the reminder today!
There are also browser extensions, which show when a website broadcasts the "X-Clacks-Overhead" - header.
I added it to all the sites at my old workplace when I was there after a discussion on HN.
One day I noticed that it disappeared, but then it returned, so someone on the inside cared and brought it back, that made me smile :)
