I am not saying one should not be careful to use * and recursive, but it's also useful to know exactly what can and cannot happen. Whether symlinks are followed recursively is a function of the program actually called recursively and often what options are used to call it. chown -HR foo * will on many systems for example try to change the ownership of files after traversing the matched symlinks.
