Just recently launched a project, the service " 
everything for a blogger ." Since OpenID is now an integral part of the blogger's life, it was decided to use the maximum: for registration, authorization, comments and confirmation of the blog.
But is everything so good in RuNet with this generally good and promising technology, designed to make life easier for a simple blogger?

After a little research, the following picture came out:
  | - commenting with OpenID
 - OpenID provider
 
  | 
It would be strange not to detect OpenID on the service from the ideologue of technology.
It is strange that on this service in general there is something from OpenID.
  | They don't know anything about it at all. | 
  | Here it is apparently also not necessary. | 
  | - OpenID provider
 - commenting with OpenID
 
  | 
It is quite logical on the service from 
Google .
Slightly disappoint the "most advanced" bloghosting.
Oddly enough, you can't comment on OpenID. I have always considered 
Yandex as the leader in advanced technologies in the Russian segment of the Internet.
And finally
  | OpenID not detected. | 
Although, if you carefully examine the code of your personal page (for example, mine - 
theifish.habrahabr.ru ), you can find such code:
<!--<link rel="openid.server" href="http://habrahabr.ru/openid" />
<link rel="openid2.provider" href="http://habrahabr.ru/openid" />-->
That in general indicates the theoretical possibility of the participation of Habrahabr as an OpenID provider.
