Very interesting question. :-)
IMHO our community is known as very technical and straight to the point. To quote Jeff himself:
I agree that TeX is so technical that nobody should really end up here
by accident.
That said, from time to time we happen to see questions that somehow tease our senses. First of all, the title was very catchy; these three words - cthulhu
| worshipping
| madman
- provoked our curiosity. And now enters in action something that I find amusing: most of us come from academia, we are researchers. We look for answers, to not only ask why, but sometimes how. So, when you see an unusual title standing out from the plethora of questions, you are compelled to check it out. And better, we are compelled to actually find a solution, no matter what the question is about!
TeX.sx
is a friendly place, and there is no place for trolling. Our humour is savvy, witty. And it's very enjoyable to read such pearls. I particulary love this comment written by percusse on Alan's answer:
That is a very calm, professional, psychopath handwriting. Mad, angry but disciplined! :) – percusse Sep 26 at 12:32
When I came up with my own answer, the whole process was funny. From the casual visitor to the active user, from the newbie to the TeXpert, it was quite enjoyable!
As a similar question, I can think of the LaTeX/Math jokes thread. The same rule applies. And even I experienced some of this curiosity that unusual questions arouse when I posted Adding slurs to words in a text; as Jon Purdy wrote in a comment:
From the title, I thought you wanted to insert ethnic slurs at random points within words throughout a text, like some bad imitation of Tourette's. The conclusions we jump to… – Jon Purdy Aug 14 at 3:17
In the chat, Andrew Stacey suggested a very witty question title. What would we do if we read a question with the following title: How do I swallow glue? I'm sure it'd have a lot of views! :-)
In short, Caramdir pointed out that Jeff wrote on Twitter about it. We got a lot of traffic from that. Also, people in general probably got curious on this "LaTeX thing" and its community of Cthulhu worshipping madmen. Even the madness has its own methods. And with a beautiful typeset, that's for sure! :-)
