What is a good response to "thank you" other than "you're welcome"?

Saying “you’re welcome” after thank you has to be one of the lamest expressions in English. It does not even make sense. Welcome to do what? There has to be something better. I sometimes catch my self saying “no problem,” which I don’t particularly care for either.

How do they handle this in other languages? The only one I know is that the standard answer to gracias is “de nada,” roughly meaning “it’s nothing.” How do the French answer merci and the Germans danke and the Russians spasibo? Funny how we know how to thank people in other languages but don’t know how to respond.
