Some men shave their head, even with a full head of hair. For the look.

Others prefer a very close buzz. A guy I work with has no hair problems, but just buzzes it all off.

Don't sweat it, men have an easy time in our society with regards to looks. And you'll soon find that getting women has more to do with your job/car/house/personality than it does with your hair.

RMS primarily uses C and Lisp. Lisp source code is a tree already. And C is so simple you can get by with tags and such.

If he was a C++/Java/C# programmer (which he is not) he may have a different feeling on the importance of the AST relative to the risk of Microsoft using gcc with VisualStuio to offer advanced features while by-passing the GPL.

Of course, but even with lisp you can't (programmatically) work on the code without having that code representation. If it's trivial, then there's no harm in opening it, but RMS thinks otherwise, so there must be something else.
