I'd be curious to learn more about how/why executives come to sign their names to this kind of writing. Maybe it feels like a natural iteration of the pre-existing experience of signing one's name to an assistant's manuscript, or a press release from staff in Comms? I don't know execs who do this kind of thing, so would be grateful for any observations others might be able to share (anonymously or otherwise).
Aside: I think it would be very good for the culture if HN automatically ran Pangram on any text-centric articles. Even perhaps just those which hit the front page? I have my own browser plugin, of course, but judging by comments here, at least some seem not to notice?
