Google+

I would very much recommend that you back up all the information in your profile if there's anything you can't bear to lose. Everything I've seen discussed indicates that they are requiring that all profiles be searchable, at least by name, which means no completely private profiles. (So Jane Q. Privacy might not have anything displayed except name, but she still has to have her name displayed if she wants any profile at all on Google. If even that much needs to be private, no profile allowed.) I suspect there's going to be a lot of deleted profiles come August 1st, because Google hasn't been clear at all.
