While I found The Verge\’s post interesting and agree with their suggestions the one thing I find missing most of all is sharing INTO G+.
Right now it\’s impossible essentially from any 3rd party experience. It\’s 100% absent on iOS and possible only from the system share intent on Android which is great, but there\’s much more … content we consume all around the web can\’t easily find it\’s way onto G+ from apps and extensions in the same fluid manner as, well every other social property.
