It seems like this could be handled by having a short post with a link to the article for each article that authors want to publish that way. This is essentially how blogs are promoted on Twitter and Mastodon already (though people often create longer threads) so it's a "paving the cowpaths" strategy. Since you can do it already, the only difference would be having an official short post representing the article, which would be a focal point for discussion about the article. For better or worse. Maybe having a focal point for article discussion is bad?
