Agreed. If they are re-investing money to grow the product, that might be why they aren't currently profitable. That doesn't indicate a lack of success in my book.
Interested in hearing more about this. Taking care of this would help with the adoption (and priority) of this project. If you have any tips, please feel free to drop a line at jherrick at gmail. Thanks!
I love my http://untappd.com and the integration with FourSquare makes me think there's a lot of potential using their API (or location data in general) to add location-awareness to an "social" application. I'm sure it's difficult to monetize that, but it's a ton of value.
Good list. I would also suggested eliminating outlying items based on prices. It seems like when there are dozens of items named XXX, there will be several with "hard drive for XXX" or something.
I must believe there's any easy way to eliminate some "outliers" using mathematics, but I can't recall the function(s) to do so.
