Google Suggest API - Too cool not to use

I'm sorry, but the Google Suggest XML API is just too simple, and too amazing not to be used. Seriously, how cool is it that you can throw any phrase against Google and trivially get back its suggestions.

For example, here's how I query for "foo is":

Query: http://google.com/complete/search?output=toolbar&q=foo+is

Pretty slick, right?

The only problem I have is that I haven't found a use for it yet. But I will, it's too cool not to.
