I found part 3 very interesting and have experienced the same thing posting work on various social media sites. Posting a piece of work on my Facebook, which is primarily friends and people not involved in the design industry, I get a completely different response than posting the same bit of work on Dribbble or Behance.
Designing for the public vs other designers vs yourself is the age old conundrum. I tend to try and find a middle ground, taking the client's personality into account. I don't have the time constantly redo/revise concepts because I'm pitching something I know makes the client uncomfortable... but I also hate making boring and ugly shit lol
I have no articles to share as I tend not to keep the links but if I come across any I'll post them here.
I think this is related to the situation where many advertising "award" winners are not actually ever used for actual campaigns (lot of stories/controversy about that). Something what works for the target audience (whether that be consumers or your client) isn't always liked as much by other industry "experts" - or even yourself.
Saul Bass was focused on designing a brand for the company and it's employees, rather than for its customers and the market at large. I agree with this as sometimes we can forget the client is the client. It was touched on in that article, it doesn't matter how good you might think your design solution is you have to convince the client to run with it.
