I love 'jj'. I would easily bet on it if I could. I know it's HN and the criticism is almost a badge of honor, but I really hope people try it out.

I also use `jj` without anyone else knowing. I get to smile a relieved smile when coworkers talk about making mistakes with git rebase/reset -f/stash. I don't sweat stacked patch sets. I never, ever, ever lose work. Ever. Never. Not even in my worst fat-finger, because of the oplog.

It's really good. Please form your own opinion from trying it. I also find the article a bit too lengthy to easily digest.
