A couple of days ago, I stumble upon a site called InstaDerby – a program that encourages users to submit a photo (via Instagram) of a certain theme and then acquire as many votes as possible by sharing the photo with family and friends.

Users submit the photo with the hashtag #instaderby and the them of the week (#springtime, for example). This week’s contest is #jam… And here’s mine!

What do you think of Instaderby? How would you get people to vote for you?
