I meant that SVN's internal concepts and workings are not simple. It's easy to use in the beginning, but it becomes difficult to even understand what's going on when you get into some kind of a tricky or unusual situation.

In Git, no matter how strange the situation, everything is still blobs, trees, commits, and refs. There are very few concepts used in Git, and they're simple and elegant.

SVN to Git is like WordPress to Jekyll - WordPress is easier to use than Jekyll, but Jekyll is simpler than WordPress.
