Surprised, and if I'm honest a little distressed, to see about a third of respondents use vi keybindings.
Absolutely amazed that so many people report using org-mode daily. Either the whole survey is primarily a survey of org-mode users, rather than Emacs users in general, perhaps because of the HN posting (I get the impression HN loves org-mode) - or nobody else uses Emacs.
Even more amazed about the questions on "completion frameworks" and packages for error checking (what?) in both of which the winning answer is something I've never heard of. I shall have to see what they're all about.
Finally - oh blimey, everyone reads /r/emacs. Perhaps that explains it all.
