For example, the graph below compares how often people entered in Google's search box orkut, Facebook and MySpace in the last 12 months. As you can see, MySpace's popularity is declining, Facebook grows steadily, while orkut is pretty constant. You can also see that orkut is popular, but mostly in Brazil and India.
Now that Google Trends has fresh data every day, it would be nice to have an embedding option. It's easy to hot link to the image, but Google could provide a mini-version of a Google Trends page that shows the graph and the refinements. Maybe they can even build a site like Swivel that lets you rate Trends comparisons, add comments and find explanations for the bumps.
Another improvement would be to automatically generate related queries using Google Sets or even from Google's live data. This could be even more useful if you could discover related queries that are popular in a region: for example, enter [MySpace, Facebook] and find other popular social networks in Russia.
