Lenguajero is a pretty bad name. It's easy to pronounce in Spanish (and is actually kind of witty) but is terrible in English if you don't know Spanish.
I'm having problems even beginning to imagine how I would pronounce Lenguajero. I definitely think you had a big naming problem and might want to consider persevering.
yeah i kind of guessed that was it, it must be pretty hard to find a word that is witty and works well in both languages.
if you guys are serious about it being a failure, im sure there are a few HNers who would gladly take it off your hands and grow it into a biz (after rebranding it of course).
I'm the other co-founder of Lenguajero.
