Writing bad articles is a great way to move toward writing good articles.

Writing in the public view is a great way to get feedback on your writing and the subjects you discuss—e.g. corrections, further education, etc. For some people, it also increase the pressure to improve.

Vanity is only one possible reason for writing in the public view, and it's an exercise with large potential gains. Your perspective is entirely off, and you've decided to take an opportunity to attack someone who was either brave enough or indifferent enough to risk being attacked in the first place.

Well perhaps slagging off the work done by others in a domain he is not an expert in isn't a sensible approach to writing articles.

People don't need to be experts to recognize flaws in tools aimed at consumers.

Sure, you don't need to be an expert to have an opinion.

However I didn't come to Hacker News to read a stream of consciousness consisting of the word "shitty" and random screenshots.

That's a good reason to downvote or stop reading, but I question whether attacking the author for having the audacity to publish the post is a good move.
