Don't have any particular recommendations, but I do have a way of browsing that made me find a lot of interesting stuff.
Go to https://dl.acm.org/conferences
Click on the Conference with the subject area that interest you, like "Hypertext and Hypermedia" (https://dl.acm.org/conference/ht)
Scroll down to "Most Popular" and sort by either Downloads or Cited.
Go bananas with reading everything.
