OK so you are using the guy's own blog, where he brags about being a hall-of-fame guerilla marketer, as evidence that his own blog is one of the most-respected blogs out there.

It's also possible that I've been reading his stuff for many years, and seen it referenced from a lot of different venues.

I'm not a marketer. His take on things isn't that big a deal to me, but he has come up with a lot of really good insights, over the years.

People on HN have been posting his stuff for at least five years: https://news.ycombinator.com/from?site=seths.blog
