OneBusAway, or OBA for those that like acronyms, is looking for feedback about their service. They have created a web survey that can be accessed here. It took me less than 10 minutes to complete and I wrote a lot so it will take less time for most people. Those who take the survey will also be eligible to win a $25 dollar iTunes gift certificate.
Besides the money this is also a chance for you help OBA quantify the benefits that real-time transit information provides. Remember OBA was created and developed for free by Phd students at UW so the least you can do to support OBA is take the survey.
