I don't think detached head is scary at all (unless viewed in another context other than git) but if that encounter can be kept away from most users without denying its use then all for the better. > With this idea there are no problems with git commands that use > detached HEAD such as git-bisect (which uses it in viewing mode, but > then skips through history, so detached HEAD is a good solution here) > or git-rebase (which does committing on detached HEAD for easier > aborting and cleanup). I do like and actively use manual committing on a detached HEAD as well, so please let's not forget about that use case. > Let me propose additional feature: "smart" (context sensitive) > warnings, namely that in the following sequence > > $ git checkout origin/master > $ git status > # On remote-tracking branch origin/master of remote origin > # ...

Too many suggestions would simply bring back confusion to the new user who at that point might not even understand yet what all the different concepts are.
