Why Do People Still Type "LOL"?
If you're laughing just type "haha" or "hahaha" or if something's really funny "hahahaha". At least that somewhat humanizes a text conversation. Typing "LOL" or "LMAO" seems like something you might get as a response from a robot who's trying to guess at how funny something is because they're in capable of possessing a sense of humor. Typing out the "ha's" and using more "ha's" to indicate how funny something was to you gives the other person a much better insight into how amused you were by what they said. "LOL", "LMAO", and "LMFAO" just don't do the job properly. You could say that by capitalizing them it shows something was REALLY funny, but that only works with "LOL". What would be the difference between "lmao" and "LMAO"? How much more can you laugh your ass off? Once it's off, it's off! Would "lmao" be the ass just starting to come off by peeling a bit like a scab? That's disgusting.
Also, "ROFLMAO" is pretty much the ultimate form of showing how much you're laughing through acronyms. After that, what is there? "ROFLCOPTER"? Now you're just being absurd. With "ha's" there's no limit to how funny something can be. You can just keep on going and going, literally typing the "ha's" until you stop laughing and that's a really great, accurate portrayal of how funny something was. With acronyms there's always going to be a grey area of ambiguity and if the whole point is letting someone know you're laughing and how hard, then I think we owe it to the person we're communicating with to be as precise as possible otherwise why even bother?
