Do you use location-based applications?

I'm a Ph.D. student at Carnegie Mellon University studying people's
current usage of location-based applications. If you're interested
in participating in an interview, please read on, or click the link
at the bottom.

We’re conducting research to understand why you use these
applications, how you use them, what you expected from them, and how
you think they could be better. We’d like you to tell us all about
your experience with these applications, and to share any stories,
ideas, or concerns that you have from using them. Do you use these
applications with a group of friends? Let them know about the study
too! The interview will last no longer than 90 minutes and you will
be compensated with a $15 iTunes gift card for your time.
