Same for me. I see it as the combination of 5 things:
1. It lowers the activation energy of getting started; for me motivation tends to come after action, and it gets me to that point.
2. It taps into the intense drive of "someone is wrong on the internet!" as per https://xkcd.com/386/
3. It's a new and different way of working so it doesn't trigger the same mental scar tissue.
4. It's vaguely social and high-status (delegating tasks, correcting and reviewing), as opposed to feeling solitary, so it tickles different reward centres.
5. More gets done for the same effort, so the cost/benefit equation is better and the feedback loop tighter.
