Ask HN: Does Product Name / domain name Matter?

I would say to an extent, yes, but not really in the grand scheme of things excepting some edge cases.

If Google started with the name ShittiestSearchEnginePossibleEverLetsStoreYourData, I doubt it would have been as successful as it is.

On the flipside, if you make a good product and your name isn't extremely obtuse, I don't think it matters at all. Cockroach Labs seems to be doing just fine.
