My son started a project using Kickstarter, a crowd funding website, to raise money to launch a headband that holds your own earbuds. I won't include the link here so this doesn't become an advertisement, but would be interested in your comments about how to get word out to the running community in general. Essentially, enough people have to go to Kickstarter, like the project, and back it with a money pledge to make it commercial. What is the best way to reach the widest number of runners in the shortest time on a limited budget?
