Google+ allows to follow celebrities (like twitter) and comment on their post (like Facebook). The result is a disaster. Time and time again, I see picture posts being plussed into stratosphere and having hundreds of comments, 99.9% of those saying “Hey, cool, Mr…. Nice photo, Mr. …” At times I wonder if Sergey is happy with this tool.
My hunch is that they are mixing private and public in a strange way, trying to lure users by providing everything what facebook does and more on top of it, killing signal by noise. Interesting times we live in.
