The thing is - it's a Social Network that's currently lacking the efficient follow/notification system at the moment that would really allow for proper use of the system. Yes there are work-arounds at the moment.
But until an efficient follow system is in place it handicaps the potential of the platform as a true Social Network and Media/Content curator.
I definitely agree. It's amazing to me that there is so much networking and connecting going on even without the tools to make it easy! That says something important right there.
