I would say that his lack of quality (dropped T on The ;] Yes I saw them too ) is perhaps supportive of his ability to be prolific "[...]make your first draft, your final draft."
I understand that you are saying that quality of edit indicates quality of thought or insight to you.
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize."
Well, there is Muphry's law.[0] Which I notice you - but hopefully not I :-) - have here fallen afoul of. Although you wrote in defence of bad proofreading; maybe there's another law for that.
Funny aside: I looked up the word “lightening” to ensure it wasn’t an alternate spelling or something. It’s not. Instead, it means:
> A drop in the level of the uterus during the last weeks of pregnancy as the head of the fetus engages in the pelvis.
The word lightening can also mean 1) to make something lighter or 2) the transfer of crude oil to a relatively larger tanker from a smaller in order to enter a port.
