There was a time (or maybe still) where some DS etc bootcamps would have their students publish medium articles as a capstone to their experience. I think both as a means of personal branding as well as researching and demonstrating subject matter competence and communication skills.
Which all sounds sensible in a vacuum, but the internet is a big, dumb machine that can’t distinguish competence (or even correctness) from expertise, and you end up with hyper specific articles like “Testing SKLearn Lasso Models inside Flask-SQLAlchemy using Mocked Spark Fixtures in Pytest” that others end up clicking on and it rises to the top of Google under some narrow search terms because of engagement, even if the substance is completely bonkers.
And then you get second order parroting of these ideas because a new grad without the experience to identify cruft actually uses them in public repos, or as the basis to hunt down and answer every SO question remotely related to this, for that sweet karma.
There are also certification authorities who offer CEUs for blogging about the subject matter. So we'll find, say, Cybersecurity bloggers who are writing about some entry-level topic, like basic networking, or types of symmetric block ciphers, and they may blog on a regular basis, because you can rack up CEUs to a certain limit by repeating a particular activity.
