Have you ever had a joke fall flat because you were trying to communicate it on Twitter, or via email, or because you were posting it in what you thought was a funny thread on the forums, but somehow other people didn't get the humor the way you intended? A lot of time that's because the internet strips away your tone of voice, or your comedic timing, or the funny look on your face, or the hand gestures -- everything you could use in face-to-face communication to make your clever joke
fucking hilarious.
This happens so often it almost seems like there ought to be an internet law about it. And there is! It gets shortened, these days, to the maxim "The failure mode of clever is asshole." Remember that. If you're trying to be clever or funny on the internet, somebody is likely not to "get you" -- they'll just think you're an asshole. Sometimes with very tragic results. You can lose friends, relationships, jobs, even spouses this way. It's happened.
I'm sure many people have made this observation, but the most famous version is probably this 2010 blog post by science fiction writer John Scalzi.
The Failure Mode Of Clever
1. The effectiveness of clever on other people is highly contingent on outside factors, over which you have no control and of which you may not have any knowledge; i.e., just because you intended to be clever doesn’t mean you will be perceived as clever, for all sorts of reasons.
2. The failure mode of clever is “asshole.”
