Puzzling Stack Exchange reminds me of this:
Can you tell me why?
A quick google search of this number gives us a result
Whose Line Is It Anyway? on IMDB. It was a comedy TV show.
This result and PSE might be related because
of the fun they both contain. Many games were played on the TV show same as many questions are asked on PSE.
EDIT: As kayzeroshort pointed out in the comments that
the show's slogan is "where everything's made up and the points don't matter." And surely many answers on many puzzles are made up and points don't really matter if we are having fun. ;)
