You know how a lot of games throughout the past, even back to the SNES, have had percentages next to each save file to show you how much of the game you've completed? Well, achievements are like that, except all your percentages for all your games are linked to one account that you can use to compare with other people's accounts. If you don't care for that sort of thing, just don't bother.
But there's no need to get irritated by the people who do care about it. That would be like someone saying "Why do you play video games?! I don't see the point, they don't do anything for you or mean anything!" It's for its own sake.
