Not sure it should be obvious you don't. Pull requests are especially well-suited for a team environment, but using PRs in a solo project can still give a higher level of structure to the progression of your code. Gives you an opportunity to explain why you're doing what you're doing.

You can also accomplish this without pull requests by writing good messages in your merge commits like you would in a pull request description.

Agreed. This approach is especially nice for situations where you open up the code at a later point, so that people can see the historic progression in more ways than just the Git history. https://github.com/thoughtbot/hound/pull/1
