I'll be honest and blunt: I try to avoid his blog posts and comments as much as possible because I do find his contributions to be super spammy. It's about the frequency of his self-promotion (as a researcher in NLP it's tiresome to constantly see his self-promotion on nearly all posts on HN related to LLMs). Seems I'm not the only one.

If he posted on the ML subreddit while I was still a mod there (left after the API kerfuffle) I would have messaged him and asked him politely to tone it down.
