Habraprofiles and subdomains ...

I noticed an interesting thing - among the Habra team members the profile address looks like this:
deniskin.habrahabr.ru/profile
whereas for ordinary Habrausers like this:
www.habrahabr.ru/people/mozaic

Question: in the bright future everyone will have profiles of the first type or Will everything remain the same?

I think with the introduction of personal blogs on Habré, the first option is preferable.

Your opinion?
