How are they forcing us to use google+?
Logging to your google account, google+ will already be setup and your IRL friends will somehow be in it. I don't understand how they do that, but they do. You don't have to "use" it per say, but they are forcing you to be "in" it. Almost everyone has a google account, given everything ties to that. Youtube, gmail, the google site itself (the only way to get rid of that stupid instant search crap unless you want to change the setting every time you close your browser). So by having a simple google account, you have google+.
I also noticed they got rid of the link feature on google maps. If you want to show someone a specific location you need to "share" it. Then it goes on your wall. So say you want to send a family member a streetview of your house the only way is to share it, then all your friends (or what google thinks are your friends) will see it on your wall.
I never used google+, yet if I login to it, I have a bunch of people in there I know or have known IRL. Some of them I've never even talked to electronically, so I don't even know how the hell they're getting this info. I also don't use gmail, so I don't have an address book or anything.... that I know of... never made one, unless Google did. I just don't get how they know who I know IRL. I blame aliens.
