When i first got here a year or so ago, I edited all the time cuz I was advised to use hashtags but I kept forgetting them. In fact I posted to ask if edits created notifications but don’t remember getting a definitive answer.
Now, I usually edit when I catch a typo—especially it’s something got a lot of attention—cuz it’s embarrassing & drives me nuts. But now that I know an edit is a pain for some, I’ll just let the picayune stuff go. I can certainly see the point of notifying those who engaged — for their own well-being.
