Have you ever seen the following comment:
/** * @author Some Awesome Programmer * */
I hate this comment, it doesn't give me any useful information, it's probably to old to give me any useful information, a lot of people have probably poked around in the code since it was originally written. What it does do however, is to cause me stress. It implies ownership and that's a bad thing when we're working collectively to create as good code as possible.
