G+ is to the internet, what Yellowstone Park was to the U.S. in 1872. A beautiful landscape where people could meet, relax and enjoy the serenity.
Recently I used this example to tell friends about G+ and compared FB to an amusement park akin Disneyland where you had to pay $45 to enter the park, $5 for a coke, $15 for a picture of you and about $200 for lunch for you, your wife and 2 kids.
On the other hand, you have G+ that is not being built to hijack your information, sell you targeted items based on your 'likes and dislikes' or anything of the sort. It is truly a social network.
Whether that makes it a cathedral or a bazaar, I don't know. What I do know is that I left FB and I'm not looking back.
