Mozilla recently revealed an add-on for Firefox called Ubiquity. Basically it serves as a command line for your browser. The catch is that most of the commands are created by users and creating commands is very simple. This allows people to flex their creative muscle and take advantage of current API‘s that are available for different sites and create really useful (and more often useless) mashups. If you watch the above video, you can see a few examples of the mashups I’m talking about. Having recently moved into a new apartment, I can fully appreciate the example where he mapped several craigslist apartment listings on a single map with just a few keystrokes. If I ever find some free time, I’d really like to explore some of the things you can do with this and whats already out there.
