Good corporate tech blogs at least give something useful or insightful for the reader and only after that they dare plug their product/service near the end.
I enjoy simonw’s posts and the discussions about them here.
Your vague unsubstantiated criticisms are very trollish and less useful, less insightful, and lower effort than the content you are criticizing.
("You keep mention your product from the start over and over" - I don't think that's fair, I mention Datasette Agent once at the start to set the scene but I spend more time talking about AgentsView than my own projects in the bulk of the piece.)
I care a lot about not wasting people's time. I never want to post anything where a substantial portion of readers come away regretting having spent their time reading it.
(OK there's an exception in that I delight in posting photos of birds on my blog, but I figure those are pretty quick for people to skip over if they don't like photos of birds!)
