The flashing red dot on the web page is very annoying. Is there some design reason for that?
edit: I meant the <svg> inside `trail-map-container`
FWIW I see the red dot only at the top of the page, flashing slowly. It does not annoy me, in fact I only discovered it because of your comment.
From what I can tell, it marks the article you're on. There are other light grey dots with other article names in it.
I think he's going for a metaphor about groups versus individuals. There are other gray dots around the red dot. Software is a group effort, but made of individuals. Something, Something.
Turning off Javascript made the dot go away.
