Over the past two or three weeks I have noticed something really interesting. I got in contact with or read about at least six startups that were all working on kind of the same project: connecting teachers, students and parents via text messages. Text messages, the old fashioned way of sharing status updated before Twitter (which interestingly enough started off as text message based service), Facebook, Google+ or group messaging apps. From inside the tech bubble this seems like an odd step back into the stone age. From the real world perspective it makes total sense.
