"Bubbl.us" VS. "VUE"

Well i just took a look at the bubbl.us website and made an account, it seems pretty straight forward and easy to use. You can also customise it i.e. change the colours and fonts. After taking a look at the website, i could see that there are obvious similarities with the application on our macs called "VUE". The main difference is that with bubbl.us can only be accessed through the internet while with "VUE" you do not need the internet. I still need to think of a topic, i'm thinking of maybe doing one that involves energy drinks.
