It's currently used in production by two online marketeers. My guess is they use it for around 20~30 queries each a week. They are currently testing it to see if it solves all of their problems (we just finished building it) and we're considering adding a 'bulk mode' where you can just upload a spreadsheet and get results back in another spreadsheet later. Thanks for the interest!
