You aren’t alone — it seems to have developed an annoying allergy to Safari, which is the browser my wife uses, so I better get it fixed. It’s only Safari, and it seems to hang at some random point while loading the articles, which makes it hard to track down. I’ve suspected it might be something funky in the sidebar, so I’ve purged a lot of that stuff (some of it was ten years old, so about time), and I’ll continue to pick away at it.
One observation that led me to think it’s something about the main Pharyngula page is that there’s a workaround: if you go to the FtB main page, and go from there directly to individual articles, they load fine. Still very annoying.
Thanks to some advice from @firstname.lastname@example.org, I may have sort of fixed the problem. It was a mundane link to Twitter that was making Safari puke. Link now hidden, blog now seems to load on Safari. Why it didn’t like that link is a mystery.
