However, if you do not want them completely hidden, because you want the number of friends to display, or maybe you want the add comment link to be the only thing that displays, then you can use the Right Column Generator for that.
This is an example of what your profile will look like after adding the code:
Categories: Myspace | Hide | Right column | Friends | Comments | Tweaks
