It's definitely part of why Cutting Words is so good.

Another fun resource is "words of Brandon" @ wob.coppermind.net/adv_search/ (linked all over the Coppermind wiki sources) - there's some interesting bits about changes he'd make to Mistborn Era 1 for a Screenplay version/if he were to rewrite/etc.

I did a recent reread of Warbreaker, which I think I landed on liking more than Mistborn 1-3. But yeah, he's generally improved over time.
