This may ruffle a few feathers, but standards that mandate templated block comments at the top of each method always bug the crap out of me.

1) They are always out of date since they are too far from the code that does the actual work to notice when you are updating things. Bad comments are worse than no comments.

2) They often just repeat information that is already contained the source control tool, just less accurate. For example: Last Modified by, list of modification date/reasons.
