I have tried that for personal projects, and more than once I have forgotten about a branch entirely. Imagine: I spend couple of days working on a feature, commit into a feature branch, tick it off the todo list, and after several weeks realize that I didn't merge it into master! And by now there are going to be merge conflicts.

The only time I branch for personal projects is when it is going to be a truck-load of changes, which are going to be hard to forget.
