There's a few historical reasons for why git was considered complicated. One of them is that it was complicated. The people who started using git very early on in order to work on the kernel really had to learn a very rough set of scripts to make everything work. All the effort had been on making the core technology work and very little on making it easy or obvious.

Generally, the best way to learn git is probably to first only do very basic things and not even look at some of the things you can do until you are familiar and confident about the basics.

Any program is only as good as it is useful.

It was such a relief to program in user mode for a change. Not having to care about the small stuff is wonderful.

Given enough eyeballs, all bugs are shallow.

Making Linux GPL'd was definitely the best thing I ever did.
