Ubiquity is
a Mozilla Labs experiment into connecting the Web with language in an attempt to find new user interfaces that could make it possible for everyone to do common Web tasks more quickly and easily
And it does, it gives you the ability to insert maps into your email by simply typing "map" and then a location and then clicking "Insert map in page" which will basically insert the map in any editable page, so simple.
Ubiquity has just over fifty commands to start you off, covering most common web tasks, such as the twitter command which lets you update your twitter status via your web browser, which I guess to people who use twitter is worth the xpi install alone.
There are already a quite a few more commands in the wild for ubiquity at Mozilla Labs Including five new commands for Transformr under the Microformats heading. If you cant find what you need and fancy creating a few commands of your own, there is a super easy developer tutorial to help get you going, still seems too much you can always watch for new commands in the Herd.
Already in just a few days Ubiquity has moved on to version 0.1.1 and development is moving on fast, if you fancy giving Ubiquity a whirl you can install the latest version Ubiquity 0.1.1 by clicking the previous link. Seems like paradise getting what you want from the web for a change? it is.
