> The fact that is it public BY DEFAULT is a no go for me. Facebook at least allows me to configure what data can and cannot be accessed by my friends,friends of friends ...

Google+ allows this as well. No way I would share my family photos with the Internet.

Also, unlike Facebook, Google+ hasn't (yet) at least gone back and retroactively made private stuff public. (They did however mess upp the buzz launch pretty badly though.)
