I stumbled across this last week and hadn't really had the time to sit down and take a closer look at it ... Ubiquity is a Firefox extension that enables a new approach to building user generated mash-ups for really useful reasons. I could go on about it, but the easiest way to understand it is to just watch the embedded video below from Mozilla Labs and jump over and read Aza Raskin's post about it at his own blog for some more details.

I am wondering what these kinds of simple tools can do for us in teaching and learning contexts. Now that we are seeing examples of things like Ubiquity I am really starting to think even more about what a powerful platform the web really is. When you give normal people the power to construct complex informational mash-ups with a few keystrokes things are getting good. I am going to spend some time playing with the early releases to see what can be done. Any ideas for a killer educational use for this?
