Hopefully we won't need PPC as we develop our sites or promote our own pages or perhaps a revolutionary new system will be in place.
I would rather have all my domains as instant mini-sites upon registration that would be dynamic sites as soon as they are activated. Sure, it may be wishful thinking. But such technology is not too far fetched to think that you select a domain name, pay for it, instant keyword selection, instant hosting, instant site dynamic feeds. Far fetched? Not at all. Look what GoDaddy does with your domain name as soon as you reg it.
The domain owner will have total control over its content and revenue generating capabilities straight from the instant it is regged. Yes, instantaneous web site and content...all in about less than a minute.
Only then will the parking companies realize, once and for all, that we don't need them but they can not survive without us.
