I read Joel Comm's book Twitter Power and it has been one of my longtime favorites on the topic. Here he talks brutally about the negatives of social media. I admit the topic caught my attention. I"ve just found that if I'm brutal about who I follow and make sure they're real educators, I'm usually pretty happy with my stream. I unfollow junk as soon as it is evident it is junk. Ultimately we all must guard who we follow or we might just find ourselves following the garbage truck.
Dead drops.com has a list of dead drops around the world. Some of my students brought this in as a maker project that they want to do in Friday's #geniushour . Honestly, I'd never heard of this and I'm not sure what I think about this. It could easily be used for great things - sharing photos or making a time capsule of sorts, but it could also be use to pirate files. It is interesting what happens when students bring in ideas.
