Took #radicle the peer-to-peer code hosting platform for a spin yesterday... WOW. Just. Plain. Wow!
Everything feels like a fairly natural extension of git itself, for someone reasonably comfortable with git at the commandline.
git push and git fetch and such all behave as one would expect, using a git remote helper.
But also did a great job incorporating patch tracking, which, again, just feels like a special git push or fetch.
Issue tracking also feels similarly familiar.
5 of 5 stars!
