This is a little broad brush. I think there are two types of aggregation going on here. One is ordinary convergence, like when common law and equity courts merged because the distinction had become a technicality. The other is more like bundling, that bane of competition.
Sharing restaurant ratings with Zagat / Local / G+ to get better recommendations in Maps is an obvious integration - convergence. Selling Likes is more like bundling. Then there's a question of proportionality - how much sharing is "bargained for". Lots more to consider...
Whatever it is I really want G+ to stay clean, professional and not invading into people's private lives...like other social networks. I really like seeing different views that are worth discussing on the world platform.
Someone said, that Facebook is a perfect tool to show You how stupid Your friends are. On G+ we are usually follow smart people and that leads to exaggerated illusion, that G+ is very cool. G+ is of course plain and simple and ad free platform and google do not need to put here ads to make for a living, because they need only information to place ads else where. Thats is a competitive edge of G+. They do not need to put ads here.
For me, FB has turned my decent family and friends into celebrity wannabes. Some of my FB friends are trying to make groupies out of anyone who'll listen. Disappointing... On Google+, I get global access to opinions and news, even if some responses are not bleeped. I prefer Google+.
+Angshuman Nandi+Adam Duda Interestingly though, FB messenger has become my de-facto replacement for SMS on my phone. It is more reliable and I can pick it up and respond on multiple devices. I'm just waiting for Google to pull their finger and come out with something less half-baked than the messaging app.
Scary also, everything you do and everywhere you go someone is tracking you and building a profile on you. Really don't like that. I would rather pay for the service or be paid for the information they get from me for using their service.
