After reading that book I found it a lot less easy to be amused by Dilbert. That experience contributed to my actively trying not to learn things about artists I enjoy. It's that "don't meet your heroes" cliche, I guess.
I had this exact experience. Growing up I had nothing but good memories of reading Dilbert over my breakfast cereal, and then laughing as I got into the workforce and realized how accurate the satire was. And then seeing what "he" was actually like just completely threw me for a loop.
I had an opposite experience. I found his comics not-funny when I was a kid, but then as a grown-up who had worked in a corporate environment, I found many of them funny.
I had 100% the same experience. I thought they were stupid when I was young, after working in an office for a year or two I thought they were peak humor.
At some point he had a mailinglist called Dogbert's New Ruling Class (DNRC) which would soon come to rule the world. In it he wrote lots of really weird, unhinged, occasionally funny stuff. At the time I thought it was all one massive joke, layers of irony and trolling. But more recently I've been wondering if he was actually serious.
I had that same epiphany when reading a biography of Ernest Hemingway.
Another type of work I avoid are "the making of ..." documentaries/accounts of classic works of film, music, and TV shows. Pulling back the curtain really destroys the magic.
I had this same feeling. Same with reading a biography of Kurt Vonnegut. Before reading it, I thought of them in idealistic ways. They had multiple affairs and weren't such great people, even though they both wrote really, really well.
Opposite of my experience. I love reading the lyrics and Genius annotations on songs I like. Vampire Weekend has a lot of good lyrics. Reading the annotations for The Black Keys' Turn Blue album was kinda eye-opening, and Kanye has a lot of great memorable lyrics as well. I feel it helps me appreciate the songs more deeply on later listens. Also it kinda bugs me if I can't quite catch some words in a song in the live-listen.
