Mr Tony's Geography Stuff

I came across something called myHistro a couple of years ago. It is a web based app that lets users create location based time lines using maps. Really very good, but students found it a little bit clumsy to use. I was so excited when I found Google's TourBuilder. It does pretty much the same as myHistro but is more user friendly. My students really like using it. So, I cannot for the life of me understand why they would make impossible to use in Chrome. Does this mean they're going to can it? I hope not!
