I would like this. I forget what site it was I belonged to, but there was one that allowed you to edit your posts, but people could still see what it said before the edit. There was a button they could click on to see it. So maybe they could do something like that on here so people couldn't try to abuse it.
Editing things would make it even more difficult for us to moderate this site. People could go in and change their answers at any time which means we'll have no way to regulate what they put in their answers after we've been through it. I really can't express how much harder it will make it for us :(
Within a limit time before first comment posted because it would be abused. Extreme example "The age of consent shouldn't be reduced to something like 10" Loads of agreement and upvotes, later poster goes back and edits question to "The age of consent should be lowered to 10" all agreement and upvotes still there, users misrepresented.
I say no, because it will surely, undoubtedly, be abused. People won't just fix typos, but actually change the meaning of their opinions and comments. Perhaps there will some way to make editing easier though, because I wholeheartedly agree it super annoying to be unable to edit posts. Maybe a system where mods can modify other people's posts when granted permission. There are enough mods to make that system work fairly well.
