So it's now a gloves off google+ vs facebook battle in many peoples eyes. I don't see it that way, they are actually different beasts entirely in view. I'm using both, FB is for the trivia and Google+ is for the important stuff, stuff I want to share with specific people who are likely to understand it rather than the self obsessed. I rarely make G+ posts public, they are nearly always to specific circles or individuals.
If you come to G+ looking for a direct comparison with Facebook or Twitter then you are looking at it the wrong way. For me G+ is about collaboration, and that's why I love it.
