Hey, great idea! I found a couple bugs:<p>1. There is not much user input validation, if any. For example, I submitted <h1>Broken</h1> to the San Francisco page, and it broke the "Explore Review Frequencies" section.<p>2. There is no checking for repeating submissions. Using a while loop on "send_review('stuff')" repeated my submission until I refreshed the page. A way to fix this would be to save an array of user ids per topic, but unfortunately that would require user login. Or, you could save an array of ip addresses, though obviously there are easy ways to get around that.
