Ask HN: Review my simple Craigslist ad tracking - first web app

Hey HN,

I'm an Electrical Eng. with an interest in web stuff. I built my first web app, www.ClassyTracker.com, to scratch my own itch - I wanted an easy way to track my Craigslist ads. Please let me know what you think, and any suggestions for improvement. Is it a tool you'd use? Would you pay a fee to get detailed stats, see longer stats, or other features? My goal was to make something so simple that even my mother could use with no problem. Thanks!
