'Mixtape' sounds retro! I used to make lots of mixed tapes. It was one of those '90s things - every girl gave them to her best friend. I remember exchanging a few with a boy on a bus when I was 14. I thought he hated me, but in hindsight, maybe he was in love with me, because he gave me the best music.
We'd all survive if Twitter shut down for a short while during major riots. Social media isn't any more important than a train station, a road or a bus service. We don't worry about police temporarily closing those. Common sense. If riot info and fear is spreading by Facebook and Twitter, shut them off for an hour or two, then restore.
It's rare that you have a policy issue that can be solved by throwing more money at the problem, but the technology to make bus service more frequent and equip buses with GPS systems that provide real-time schedule updates to bus stops exists and operates in many parts of the world. We should be installing it in our major cities.
