How does Share your Spark work?
The challenges offered should be clearer in detail. I know I get a share whenever someone scans my QR code, but I find that looking for other user's codes to be tedious and unrewarding. I only found one other user on Spark and the personal site did not contain his/her QR code. You should make the Spark game easier to play. Maybe include a tutorial video or a manual, or a FAQ page.
