In the right-hand navigation bar of the site, there is a "Tags" box which lists the most popular post tags. This box has a feature whereby the tags are rendered in a font size proportional to their frequency of occurrence.
Over time, the attribution of the "sequence_reruns" tag to sequence rerun posts has made this feature inoperative: because it's the single most used tag, and no other tag even comes close in frequency, every tag is now rendered at precisely the same font size except for "sequence_reruns".
Some tags such as “meetup”, “psychology” or “rationality” do appear to have a slightly larger font size, in my browser at least.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
