I agree. Have you ever tried to spell stackexchange.com on the phone - maybe even to a non-english speaker? It's not a great name, and some of the alternatives should be within reach for a company that started with $28M of venture capital.
However, there doesn't seem to be much interest on SE's end to do anything about the domain name - not even the stackexchange.com umbrella. The only official response I've ever received to some suggestions I made was a comment from Jeff about the "shit's easy syndrome" with no explanation.
