In fairness, I think reading abstracts is a good way to 1) quickly gain information and 2) figure out if the paper is worth the time to read. Especially for paywalled papers, and when I'm trying to get a broad sense of different ideas, consuming a few tens of abstracts is a nice way to get a feel for the research.

On a somewhat different note, I also tend to only read the comments of HN threads and Youtube videos...
