I just executed an "Exodus" request from this service, and it is still up and running and working as of 4:41 PST.
Since Facebook hasn't blocked this application as of yet, I wonder if Facebook is taking the stance that the more people that see Google+ now, the more people might see that Google+ isn't as useful and polished as Facebook.
I love Google+ and am an active user, but they still need quite a few more features (checkins, business pages, iOS integration etc) before they'll be hitting their stride for the masses.
Regardless, this has been a fun month of July!
