I believe this site is missing a very important thing, direct links to the different categories with a list of papers. This is at least how I (and I believe many others) browse arXiv. I open it up in the morning, scroll through a few categories and open a few papers that look interesting to me.

I could see myself using alphaxiv for that, and then, if there's a comment section, I might even read it, and, who knows, leave a comment. But there's no way I'm going to be changing the address or going to some other site to search for papers just to see whether there are some comments.

ps: I see the extension adds a "discussion" link to arxiv, it is a pity that it is only available for Chrome.

It sounds like what you want is scirate. As far as I understand from this post this new thing is just scirate but lacking the interface you're talking about here.

Indeed. Scirate (I didn't know about it) looks exactly like that.

Sadly, the last comments in HEP are more than 2 years old (which explains why I had never heard about it, it seems it never gained any traction)

Kinda related, Hypothesis (and Diigo iirc in past) has an extension/bookmarklet that can provide an annotation/comment overlay on any web page/pdf. Guess what is needed for arXiv discussion is this overlay but smarter, that is knows a paper pdf and web view are the same, and abstract page is connected to them.
