There’s an old adage about never meeting your heroes that applies well to PG. Some of his daily takes were so embarrassing and insipid that it was hard to maintain respect. It’s funny because his long form posts which are often insightful were likely reviewed/edited by a third person. A concept he has actually said only exists in the modern commercial publishing era.
I've met PG at a book signing and he was quite pleasant. I asked about when Arc would be released (this was a while back) and he laughed and joked about it. Really nice guy. Do you really think twitter equates to meeting someone?
That really is one of the worst parts of Twitter. The form of short-form drive interaction encourages some of the most pithy and dismissive conversations and leads to some really hostile interactions that often dispense with human decency.
(I mean, not restricted to Twitter, I've experienced it here, and on Mastodon, but Twitter really takes the cake.)
