There's a thread online where people are talking about cultural things that "quietly went away without anyone noticing." They include:
2. Facebook "poke wars"
3. "When you turned off the TV, how the image would shrink to a dot before slowly fading away"
4. Flash mobs
5. Traveler's checks
6. HQ Trivia
7. "ROFL" . . . now we just go straight from LOL to LMAO. (Maybe because we're in a post-COVID world, and the floor might be dirty.) (???)
10. Those black plastic bases on two-liter soda bottles.
