This is perhaps due to a few fairly large recent deployments:

• BrightKite.com - all venues and user profiles have hCard (millions)
• Gravatar - all profiles now have hCards (millions) - used on WordPress.com etc.

There's also been a notable very useful deployment from 37 Signals:

• 37 Signals have added hCards to Basecamp:

Thanks to Jeremy Keith's help!

• StatusNet platform uses hCards for all users and groups (Example instance: http://identi.ca/ ). Also uses representative hCards where appropriate. I'm not sure about exact numbers --Sarven Capadisli 22:51, 7 July 2010 (UTC)
