Does Randall realize the power he has? If he wants something to be made or done, all he has to do is post a drawing of his idea, and someone brings it to life.
Notice also how many involve nitrogen - and you're breathing that right now!
Like nitrogen, the nastiness of flourine is potential. Most actual flourine composites, including those proposed to be used in reactors, are quite stable.
Watching Randall and moot at ROFLcon I felt the same thing. They both have quite the power over their audience. Randall just needs to draw it and moot just needs to say it.
My first thought. Has anyone been tracking stuff that started as xkcd comics? I only recall a couple: self referential chart, Facebook group of million users, MBR love note, people playing chess on roller-coasters, sudo make me a sandwitch robot…
Looks like http://en.wikipedia.org/wiki/Xkcd#Inspired_activities is missing some.
