I find myself using it less on lemmy, but I think I have used it on occasion here, just to help to "distance" myself from whatever crazy shit I've commented. Ever since 2016, it's been a necessity when you can't rely on people to assume you're not as batshit crazy as what your comment reads as, which you really can't assume of anyone anymore. I've had plenty of times where I wrote a sarcastic comment in order to make fun of an idea, only to have people (who I'm pretty sure actually agreed with me) explicitly make the point that I was attempting to make through sarcasm, but they're attacking me because they think I'm an idiot (which is still possible).
