Notes:
Jesse June is a glamour model (!)
Vic Gundotra is a techie at Google
Trey Radcliff & Thomas Cook are both photo bloggers
Dane Cook is a comedian & actor
Felicia Day is an actress
Ron Garan is a NASA Astronaut
Tom Anderson is 'Tom from MySpace'
Mark Zuckerberg has seemingly never added anything - people just think it's amusing to add him
Compare to the Twitter top 10 - 7 of those are women, only 4 of the G+ top 10 are; Britney Spears is the only person to appear on both lists.  The other striking things are that it's still comparatively 'techie' and photography is popular.
