Why do you use this service? My dream for the site would be that the most value would come from the comments section where people could ask questions, discuss ideas, expand on the background of papers, or debate whether the results justify the conclusions. I'm also hopeful that much like HN, the site wouldn't track the newest and shiniest thing but also would highlight older work that is worth revisiting.
You cherry-pick results and polish them to look super flashy so everyone hears about your work over Twitter, Facebook, and r/MachineLearning cause that's how everyone learns about new papers these days.
If you add comments, then you get to the problem of maintaining comment quality which will likely lead to some form of moderation. IMO that leads back to the "cliquey" issue just on another level.
