This is really cool! If you haven't discovered Trackle yet, you should check it out. I started using it to to get notified about new NY times bestsellers, news about my favorite authors, and to track where my name is coming up online and in blogs. And there are so many other things that you can track too.
What a great tool! Because honestly, who has the time to do all that "tracking" ourselves anymore.
And the best part is that it's free!
