Lighten up. You know what's funny - is that I have tons of friends in work, on multiple private slack groups and all over, guess what - we all joke.
That's what make us friends.
I'm not here to prove myself - I participate in the tech community here and it's like everyone like you just tries to put on some superiority complex and act like tech is ONLY serious business.
I've seen plenty of jokes that were good, relevant, and tasteful upvoted on HN. Do you think it is possible you are mistaken about the quality of yours?
