I love the idea of Fossil -- tools like a wiki, issue tracker, automatic synchronization, all built in, plus the more resilient on-disk format, are features Git should've had from the get-go (no pun intended), and having everything, web server to CLI wrapped up in a single binary is an extremely cool way to do it.

I want to switch to it, I really do, but git commit --amend is just not something that I am prepared to live without
