If he's added 200 friends in the last month and has a bunch of friends that he doesn't actually know (since by his own admission, he doesn't turn down any friend requests), then he's using Facebook incorrectly and it's no wonder he doesn't find it useful. Facebook is at its best when you can see what's going on with your actual friends. If you have hundreds of non-friends cluttering your feed, that interest evaporates.
