I agree that the @param adds some weight to the code, but it doesn't really bother me.

What I like of it is that it adds some form of standardization, both for the form and the content. Currently, function headers (when they exist) are usually one paragraph that sometimes describe some of the arguments. This format makes sure you have at least one statement describing the function and then one line per argument. If the structure of the comments is always the same, it might actually be easier to read, even though it's more text.
