Agreed. Even as the second cctld of the USA, with .com being the first one , .us should be doing much better and all it needs is a little presentation and marketing. People go nuts of Columbia or some island extensions, while .us provides businesses with something those cannot provide: trust and memorability. People here in the USA are conditioned to remember .us extension as lots of government organizations, small businesses etc. are on .US. They also don't experience much scam with .us, as it requires residency. Zoom.us might be doing the greatest service though, by using .us and even forwarding .com to it.
