Here's why I think it's working so well, as someone who's participating in llama.cpp development and who has participated in many other open source projects:

1) Reviews are super fast. Sometimes I get the first review 5 minutes after submitting a PR. Today I had a PR merged with two reviews within 42 minutes. This is incredible work by the whole team. It keeps contributors motivated. The pace is intoxicating. On other projects, I've sometimes been waiting months for a review.

2) Georgi motivates people by giving them responsibility. There's no gatekeeping as with other projects. He happily delegates. You do good work? It's appreciated, and you get the freedom you need to make an impact. That feels awesome.

I've rarely become addicted to an open-source project so quickly.
