This is a table of contents. Those are the names of sections. You can click on them to go to pages of more normally formatted paragraphs.

The paragraphs on all pages are formatted quite narrowly, displaying only 3 - 6 words per line.

If this bothers people, it can also be changed with Stylebot or the like, using a rule like this to change the max-width, which is set to 400px, to a larger value:

p, ul, li { max-width: 800px; }

Thanks - my mistake. I thought this was some really bad LinkedIn style content.
