Idea: VR/AR won't take off without a means of publicly-accessible asynchronous communication. What newsgroups and the WWW were for desktops and laptops, what microblogging and video hosting sites have been for smartphones, something like those media has to come for VR/AR devices.
The closest I've seen to asynhronous VR/AR are virtual world servers like #SecondLife and #OpenSim. #Sansar might - might - come through when its released.
