If you use Stack-Overflow today, you will be surprised to see this popup:     This has caused an explosion of Reddit comments here: https://www.reddit.com/r/webdev/comments/mhkume/stack_overflows_new_copypaste_limit/ When you click on “Learn More”, you get to see this : Aha, 3 keys for $39.99 … riiiight 🙂   If you click on the “Pre-order” you get to see this:     April Fools joke. Hahahahah 🙂     But those guys from Reddit didn’t laugh, at the beginning. 🙂
