Quanta magazine always has clickbait-y titles, you can tell when a Quanta article reaches the front page without even looking at the source URL. Do they seem more popular recently to anyone else, or am I just starting to notice it now?
I've noticed too but I think it's just the classic self-sustaining HN cascade where posting a website triggers posts from the same website, or on the same subject, because people find other interesting links in the comments or on the website itself.
