I give the idea to write a script for Google Buzz!
The script should hook up the link to the Google Profile of the user and pull out the name, this is exactly the address of the gmail box.
For example, http://www.google.com/profiles/
pupkin.vasja #buzz
Email address
pupkin.vasja @ gmail.com. The script should insert the icon and link (

) next to the name.
The script should work on the basis of
Chrome Extensions or
Greasemonkey .
Example:
