That's true, but I made that statement about XML parsing based on my own life experience: I love working on version control tools, I'd work on them even if nobody else used them. They have this internal beauty to me, but most people have just decided I'm a little nutty for liking that kind of work.
You are in fact nutty, but are still trying to solve a problem no? Sometimes we solve problems because the solutions are useful, and sometimes we solve problems because the problems are interesting. I think most of my personal coding falls in the latter category.
