Oh wow. More stupididty.
You arguement is meaningless. XML markup of comments has nothing to do with the quality of those comments.
Bad comments are bad. Good comments are good. Good comments with meaningful markup are better.
Comments don't suddenly become bad when you add extra meaningful information to them that identifies exactly what the comment is for.
If you can't see why the ability to have a standard meaningful way to document a function paramter is a good thing, you need to stop "programming." If your comments aren't good enough to provide even basic useful documnetation, then you suck at commenting.
In summary, just because you are bad at something or don't fully understand it, does not make that thing worthless.
