The purpose of my research to better understand the extent to which people use grouping mechanisms in online social networks. Please consider filling out the survey. It will take about 10-15 minutes to complete and covers Facebook, Google+, and Twitter. Here is a link to the survey: https://www.surveymonkey.com/s/WGYYKGF Thanks! I really appreciate it!
