Duality

Oh, they've been talking about doing that for decades.

As for dangling gerunds, they're a terrible grammatical error involving the misassociation of nouns with a gerund. For example, in the sentence "While drinking our coffee, the lions approached our camp", the word 'drinking' is a gerund, and is mistakenly positioned in the sentence in a way that makes it look like the lions are the ones drinking the coffee. The sentence should read something like "While drinking our coffee, we saw the lions approaching our camp", where the gerund 'drinking' is correctly assigned to the noun 'we'. It's a messy business that often trips up padawan authors.
