Hot Spots Business or fan log their local spots and print a QR voting code to put up at the place ("vote for us!")- then nightly (or during the weekend) people vote by scanning the QR code at the spot (probably would have to make an account to vote), places with the most scans are listed as Hot Spots. the hotness goes down after a few days, unless ore votes come in - you can also do metrics on most visited, best weekday spots, etc. Plan to do this myself at some point.
