So, Hackernews, here is what I want you to do. Create a website with "solve this with your editor" challenges where everybody can upload screencasts and compete. :)

An obvious metric would be /time to completion/ but I would also be interested to see /can be done with mouse only while drinking coffee/ or in general /can be done one-handed/, /can be done left handed/ (so the mouse is free) or maybe /keystrokes+clicks/ instead of general timing because it takes the typing speed out of it. Some metric that measures how many shortcuts you have to memorize would be great, too.

Now somebody go and do it! :)

There's http://www.vimgolf.com/ which is obviously focussed on Vim, but there's nothing stopping people from keeping a scoreboard of the same challenges for other editors. For example, the Kakoune editor has their own: https://github.com/mawww/golf/
