For elementary students, I really like how you can add an image to a button so it is easier for them to find it. Here is the start of mine.
Once I make it publicly available, I can post the link on our class website. I can easily share it through Facebook and Twitter. I can also add it as an app on our Joli Cloud for the netbooks in the room. I still have to find out if this would also work on an iOS or Droid-based tablet. You can also add it as an app in Google Chrome. If you can use it in so many ways, this may be a great way to get links out in a BYOD classroom.
