While I don't think it's practical to expect every paper author to write in the most consise and elegant style possible, one thing I do wonder is the lack of a "comment section" for papers: why isn't there a centralized place for academics to just leave comments or their understanding of the paper, like most of the web forums? I don't expect the author to respond or even be active in every comment section but there should certainly be such a place. Every other form of Internet-based discussion, including Reddit, any random Internet forum, mail lists, Discord, etc. are all interactive and everyone is expected to participate in a centralized and public discussion. This way, even if the paper itself is hard to read, for the good ones I do expect someone else to leave a comment with a sketch of the most interesting parts of the paper that would get upvoted to the top, and the author could click a "promote" button or something to make it official. This way the author doesn't have to write very well as long as the paper is valuable enough for someone else to be interested.
