I too am with Namecheap after getting totally disgusted by Godaddy's terrible interface. I'm very happy with it. Plus, I think Namecheap was actually cheaper than Godaddy for my .net, anyway.
I've had several domains with Namecheap - never had any problems whatsoever with them, and as far as I know they don't have the lack-of-ethics baggage several of these other really questionable registrars seem to have.
I estimate I helped 50-some people to switch from GoDaddy to Namecheap after GoDaddy's last meltdown. I haven't heard any complaints, and they're all happy not to be doing business with the likes of GoDaddy any more.
I think that the application itself has a lot of potential; however, there are two things that distract me from the actual content. Although I find the design agreeable, I feel as though the color scheme is reminiscent of security, perhaps Norton AntiVirus even. Although this could be seen as a positive, I think it is too much business/professional given the concept and would benefit from a more design/art feel. Additionally, I agree with mryan that the name does not do the application justice and quite possibly gives the wrong impression to potential users. Below are some available domain names I just brainstormed if you are interested. I am not suggesting that these are necessarily any better, just offering some suggestions. I hope that this does not come off as too negative, as I am honestly impressed by the application thus far. Nice work.
