Why do we need a domain? Bitcointalk.org is enough.
Um... because it's BITCOIN talk? And where are you planning on putting the client if not on a domain? How do you intend to market your currency and separate yourself from Bitcoin... if not with a domain of your own?
Using bitcointalk is fine for now, but if any altcoin really is serious about success, I think it has to break free and create a space of it's own. Otherwise it would be like Apple trying to market their products on Microsoft's forum.
I have to say.. I thought you were serious about creating a real contender to Bitcoin, but seeing you write things like this makes me lose confidence and see you as an amateur instead of a professional.. in other words; not a "business" I want to invest any more in.
