Hi John,
I under rationalle behind not allowing people to perpetually edit their posts. I think the new limits went too far. I believe you only have about 10 -15 minutes to correct errors in post right now. Most sites allow at least 60 minutes to 5-6 hours for a post to be edited.
Sometime you'll re-read a post later on in the day and you'll notice a spelling and grammar error in the post that needs to be fixed. Now you can't fix the post anymore.
Is there any chance you'll consider extending the edit time on KG posts to at least a couple of hours to correct minor errors like adding another image, grammar, spelling, ect..?
