Google plus

[seoug_2005]

"Google+ members, and to a lesser extent others who are signed into Google, will be able to search against both the broader web and their own Google+ social graph. That’s right; Google+ circles, photos, posts and more will be integrated into search in ways other social platforms can only dream about."

What is meant by " and to a lesser extent others who are signed into Google"  ?

Does it mean that non-google plus members won't be able to view Google+photos, posts ?

I think this means they will also possibly take data from services such as PIcasa which you don't have to have a Google+ account for... just a Google account.
