As unnecessarily snarky as this person is being with you, don't let a HackerNews comment stop you from being an great person.
If that's just the way you like things, sure, that's what personal sites are for. How you like it. I apologize for implying otherwise (it must come off that way since two different people took it that way). I just really dislike the web as 'executable application distribution layer' model and try to stick to websites that are HTML pages.
I believe that in my case, the use of JavaScript is justified because it's information that doesn't require a separate page; there are just a couple of configuration buttons. On the other hand, the page is rendered using HTML over WebSockets, and what you're experiencing is the vanilla SEO version... hut of course, that's just my opinion.
