> The frontpage should directly show the list of papers, like with HN.

I disagree. There are numerous times where I have browsed the comments on a HN post where people haven't read the article and are just responding to the comment thread. The workflow for this seems a bit different in that a person would have already read a paper and wanted to read through existing discussions or respond to discussion. With that, having the search front and center would follow as the next steps for a person who read a paper and wanted to "search" for discussions related to that paper in particular.

HN is more an aimless browsing which is a bit different than researching a specific area or topic.
