I was thinking specifically of the AI/ML folks. Many top researchers from universities, google, open ai, fair, etc. are super active online. I don't think they do it for career visibility.
There's a cargo cult blogging thing going on in ML, where you also have a large number of tutorials written by variably-competent people written not to inform, but to look good. As I'm sure you know, the results are fairly mixed.
