Have Google Just Demonstrated the World's Biggest Social Network?

...or am I just nuts?

Probably

Have Google just shown their hand in the big social network gamble?  And has it been there all along?

Okay, so I may sound like an insane conspiracy theorist, but with the update of Google Profiles - the quiet backwater for the geeks and profileistas - Google seem to have shown us what a social network really looks like.
