re: Google+ Satisfies While Facebook Slides
People are accustomed to trusting Google with email, and getting what they need when they pose a search problem. The search problems are about 5 to 10% solved at the current state of search, and an entire generation of young people have now been using google for 15 years, and in the business marketplace, millions are using Google Apps in the enterprise.
All this adds up to long term companionship and trust, and granular, easy to use control of your circles of contacts. In short, there's a reason people monetize using Google- the Zero Moment of Truth- or search ads that are presented while you are looking for a solution to a search problem, as opposed to when you seek to be entertained by party pics, like Facebook is doing- it's simply not a good time to reach people with ads.
