Really the big win (for individuals) would be a one click unified domain registration, social media signup, @yourname.com email hosting and About.me setup.
The video you've made shows the current path of least resistance to setup your online identity (at YourName.com), but I can't help but feel it requires more effort than it needs to. Eg. navigating GoDaddy's aggressive upselling, DNS management, etc.
Have you seen IWantMyName.com? They're trying to simplify some of this.
On the other hand, Flavors.me is like About.me but also offer domain registration as a part of the signup.
Finally, when it comes to using a personal domain, my instinct (and most others I'm sure) is to find free solutions for every aspect of the domain where possible.
On my personal domains I use:
- Google Apps for email and private wikis (free, I'm well within the free usage limitations)
- Tumblr for my blog (free, including pointing my domain to their service, I love that about Tumblr)
- Montastic for monitoring (free, my needs are quite simple and they'll happily monitor a couple URLs at somewhat infrequent intervals)
I think the point I'm trying to make here is that I'm onboard with you in terms of personal domain advocacy. However in terms of a business its probably tough to simultaneously offer a very low effort solution that provides a good overview/perspective on the individual using the service (eg. a nice default personal profile page) and make money given people's propensity to use free solutions for their own domain.
Check out the recently launched BrandYourself.com, they're doing something cool that is really in line with your thinking, I wonder what their traction is like (I use the free tier - surprise, surprise).
