I can see that, but remember that "Google" and "Yahoo" hardly sounded like uber-mature names when they came out either. They sound like serious products/companies now, but that's merely because of their sucsess.
A fair point. I still think "Yahoo" is a dorky name, but perhaps that's because I don't really understand why they still exist. Google, on the other hand, has earned my respect and thus I have stopped noticing what a silly name they have.
I think one fewer syllable and fact that neither yahoo or google were commonly written (or said) make them better names. I use DDG, but think the name is terrible. It also can't become a verb as easily, as google has.
