> They also made the mistake of showing a link that includes the word "Typography"

Including some aesthetics-stretching cases seems like a fairly honest/transparent thing to do for an open-source project that someone is blogging about.

That's a reasonable way to look at it, but humans like us can be pretty flexible with semantics, thanks to pragmatics. If I see a link that covers most of a set of letters stuck together without a space, I tend to assume that the whole thing is a click target. Even if my assumption is wrong, my clicking error rate probably won't be too high, since I think that people tend not to hit the edges of pointing task targets.
