http://www.flyte.biz - Sparks are your "areas of interest" in Google Plus. In other words, they work a lot like Google Alerts, but are available through your G+ account.
You'll find the Sparks links in your left hand column. By clicking on Sparks you'll see a number of pre-set Sparks that Google has provided. Seeing how one of them is Cycling and the Tour de France is currently running, I'm guessing these will change over time.
You don't need to let Google choose your Sparks, however. Just type in any area of interest in the Sparks field and Google will start retrieving news stories for you.
