The dh just asked me, "Do I say, 'More facts can be found at (or on) this website?"
I said, with that perspicacity and sagaciousness that get little credit at home, "They can be found AT the website, because they are ON the website."
What do you all think? You can understand why English prepositions defeat the most fluent non-native speaker... well, even the native speaker, because I don't know either.
Not that I'm going to let the dh know that I'm not sure I'm absolutely right. :)
