Think so? It's not a word and doesn't mean anything to me. I can't imagine having to tell it to someone in person. Anytime you have to specifically spell out your startup url, I think it's a problem.

Cool site though.

In Spanish, "Vaya" translates roughly to commanding someone else to "Go!" Granted, not everyone knows Spanish, but it's not totally out of the blue.

Is it the same pronunciation as "viable"? Or is it phonetic "vay-a-ble"?

The former is the correct way to pronounce it :-)

Seriously good name. Was it unregistered? I'm nosy.

Yup! Probably one of the last "-able"s left :)
