How Google+ Shows That Google Still Doesn't Understand Social (opens in new tab)

I disagree with the author. I see no point in making my conversations accessable for everyone, especially if they cant actively participate in them.

There is no need in grouping your friends in any way, just create a circle with all your friends and those will behave the same way facebook does,at least if I got it right (by the time I got my invite it was already full). I think there is a difference in what I want my friends and family to know about me and what people I just know but have no deeper relationship with should know. Posting something publicly would make it accessible for everyone, twitterlike.

It should be pointed out that the author currently is employed by Facebook, and is not an impartial user commenting on the rivalry.

That said, I found it hilarious that the author went on a defensive tirade for half of his post trying to somehow undermine the "Public" option when you make a post on Google+. It appears he completely missed the point of it being Public: that anyone is free to view and/or comment on it, along with your friends. That's what Public means, and there's a reason it's off by default.
