In that case, yes. But what if the domain is somedudesname.com and that is the blog of some company's CEO? It'd be preferable to have a title like "XCompany changes direction, elects new leader".
Being right or wrong about dismissing a bad example doesn't matter. The important thing is to fix the example and then evaluate it.
I guess I have a problem with jumping on someone who was correct.
Perhaps a way to get around the ambiguity (at least in case of github) would be to encourage people to use/link to gh-pages (so we see github.io as distinct from github.com) when they are available?
