> Is there a good explanation of Jujutsu without referring to git?

There can and will be, but at this stage in the project's life, git familiarity can be assumed.

> Am I the only one bad with memorizing SHAs when reading?

Nope! The CLI has nice syntax highlighting to show you the shortest valid prefix, so for example, right now I have something that looks like

  lzrvnkxl
but the initial l is in purple, while the zrvnkxl is in grey. This means I can just use the l when referring to the change. That can be harder to demonstrate in a blog post, which can't know how to highlight this, and so often they have no highlighting.

> Also, does it work with other people? Would it work in repo with 5 contributors? 20? 500?

Yes. Because it's backed by a git repo, nobody else needs to know you're using jj. Everyone can use the tool they choose.

This is such a simple UX feature that I have ended up using all the time after I switched to jj a few months back.
