I came here to include a picture of the kakoune.org problem, but since you already have one I'll include a (hilariously?) similar picture of your tweet.
On the subject of kak, I tried it a few months ago and thought it was really impressed by it but didn't stick with it long enough to decide if it would be better than vim for me.
