It is against HN guidelines to post complaints like this. We all had the same experience reading the article; yes it sucks, but it sucks in a completely common way that has nothing to do with the unique content or why it was posted to HN.

And complaining about it here adds no substance to the conversation, nor does it do anything to fix the problem.

In the spirit of the subject of the article, perhaps view the terrible UX as a sort of difficult wilderness you have to cross in order to reach the interesting info in the article text. Take pride in your ability to forge ahead and reach your goal. :-)
