Google is removing the only grounds for someone to use Google+ over Facebook
Back when Facebook first started this kind of crap a fair number of people joined Google+ hoping to pull everyone away from Facebook because of what they were doing. I joined and ended up having about 20% of my Facebook friends in my 'circle' or whatever they call it.
I think it was over this very issue that many of us joined Google+ in the first place, but Facebook pisses people off and makes them threaten to leave every six months or so, so than a few tentative waves of people creating an account on Google+ hoping it might reach critical mass and replace Facebook, few ever actually leave. We just tighten our privacy settings after they undo them, or stop doing things that will cause problems with the new shit they're pulling (i.e. I unliked all but a handful of local businesses so I won't appear in ads on other people's feeds)
If it weren't for Facebook constantly eating away at privacy Google+ could have never got off the ground. Now Google is effectively killing it - why would anyone ever login to Google+ again (I only check it about every other month anyway because nothing ever happens there) when its policies are clearly on the way to becoming just as bad as Facebook's? At least with Facebook I actually have friends there I can keep in touch with, versus the tumbleweeds blowing around on Google+.
I should probably delete my Google+ account, but I think I'll leave it up to see how long it takes before Google shuts the doors. Since my myspace account is still around even though I last logged in in 2007, it might be a while. Guess it doesn't matter since I probably only posted about three things on Google+ anyway!
