I meant "Lite" because Google / Eric Schmidt et al are lamenting that they did not go after FB more intensely. They see the future, and it's not them. The threat is real, and to date, the Google Social Networking efforts have failed.
I agree with you, this is not the same, but what I see is Google simply coming at it from another direction, and this is one step along that path. Look for more steps in coming months, then at some point, an attempt will be made to tie it all together into a kind of social network.
"Do you like the Baltimore Orioles baseball team? Great! Join other Bird fans ~ just click a +1 at any site you visit and you can be in instant touch with other Oriole fans from around the world. Join the PlusOne Club now!"
(For the record, I made up that quote)
It's going that way ~ yes, Facebook Lite ~ you read it right.
