I prefer the question about CPU pipelines that gets explained using a railroad switch as example. That one does a decent job of answering the question instead of going of on a, how to best put it, mentally deranged one page rant about regexes with the lazy throw away line at the end being the only thing that makes it qualify as an answer at all.

The regex answer is from the very old days of Stackoverflow, before fun was banned. I agree it barely qualifies as answer, but considering that the question has over 4 million page views (which almost puts it in the top 100 most viewed questions all-time), it has reached a lot people. The answer probably had much more influence than any serious answer on that topic. So I'd say the author did a good job.

For anyone wondering about the railroad switch post: https://stackoverflow.com/questions/11227809/why-is-processi...

But--and this is crucial--the one about regexes is hilarious.

It also comes from a time in Internet culture when humor was appreciated instead of aggressively downvoted.
