Yesterday Google has sent me a e-mail that they miss me and my reviews on maps. I'm a "Local Guide, level 6" and have contributed lots of reviews/photos/ratings/answers to question, but I won't contribute anything anymore: There has been a unspoken agreement between Google and it's users: The users contributed content/data freely, Google used the content and gave back awesome services free of charge. Google broke this agreement repeatedly - Reader, and Google+, in a very cavalier fashion: Just a "Oh, by the way, we'll close Google+" in press announcement concerning a security problem.
Why should I contribute contenct to Google or invest time and work to write well-balanced reviews when Google+ antogonizes it's most loyal users? Who says that the local guide program won't be terminated in a similary way meaning all the work wil lbe flushed down the john?
Nope, Google, if you want reviews/ratings do it yourself. I'm done with you.
