What's difficult is reading threads, or more broadly replies. But single posts? Absolutely fine, in fact it's about the only thing that is totally functional without being logged in.

Oh, weird. I didn’t think there was a way to get rid of the pop-over that hides the post on iOS Safari. But it turns out that there’s a button to close it, just, completely disconnected from the pop-over and hanging out with a bunch of unrelated UI.
