My opinion on G+ (based on about an hour of tinkering) :
- G+ will be of limited utility until the majority of people I know or care about is using it (ie. it has to catch up with FB and Twitter)
- Circles – great start but needs finishing – need more set theory – subsets, intersections, compliments, etc. will make it very powerful though maybe a little nerdy for the non-technical.
- UI is very slick – amazing demonstration of what is possible in a standard browser
- I represents a personal dilemma. I’ve been using Facebook for mostly personal stuff; Twitter for mostly work stuff. With a little natural overlap. I can manage two social networks; three will be tough.
