Facebook, of course, has a huge head start, but there are good reasons for people to seriously consider dumping Facebook for Google+. [See our ]

The biggest wedge Google has for driving people toward using Google+ is integration. That is, Google will build Google+ social networking features and tools into almost all of its existing online services from Search to Documents to Video. Google+ is already integrated into the navigation bar at the top right of almost all Google products; this lets you monitor all Google+ events (updates, messages, etc.) as well as share content with friends without ever leaving the Google service you happen to be using. Millions and millions of people use Google's free services (Gmail, Docs, Search, etc.), and with Google+ bound so tightly to them it may start to seem silly to jump out to some other site (Facebook) to do your social networking.

Google is right that the "Circles" concept is more in line with the way we make friends in real life. We have many different kinds of friends, and we interact with them and communicate with them in very different ways. Facebook's Groups feature lets you form ad hoc groups of friends, but compared to the way its done in Google+ it . After all, Facebook's Groups feature is pretty new; it was "built on", while friend "circles" are the bedrock of the Google+ platform.
