On the Murray State University (MSU) campus, a social media application called Yik Yak gained popularity among students in 2015. Curiosity led a few librarians to download the app, and we were surprised to discover that our libraries were frequently a topic of discussion. Users posed questions about our hours or services or complained about the facilities or resources. Monitoring the feed has enabled us to surreptitiously eavesdrop on the user experience and to potentially use what we learn to improve our services.
