The tool that this writer created is totally cool and totally creepy. I love it because it’s sort of a conundrum, and the writing is also hilarious:
You know those green dots on the sidebar on Facebook that tell you who’s online? How do they get there? Also there are times next to people who are offline. What are those about? I was wondering the same things, and so one day I decided to 360 noscope hack Facebook by right clicking and selecting “Inspect Element”.
