You're being a bit unfair. Wikipedia does have a goal, and ignoring other valid goals is not really a valid criticism. Wikipedia doesn't strive, for example, to end poverty or cure cancer. Their goal is to build the best and most freely available encyclopedia. You just seem to have an issue with what an encyclopedia inherently is, so I suppose Wikipedia becoming the best instance of an encyclopedia doesn't appeal to you.
Yahoo tried to replicate business directories on and for the web, Google did not.
