I collected some data using social media platforms recently – specifically, I asked for participants on Facebook, Twitter and LinkedIn. 80% of the replies came from Twitter. I am trying to explain this ‘skewed’ response rate. Do you know of any suitable references?
This is a good question to raise in the social media research group. http://www.methodspace.com/groups/nsmnss Do you want to post it there for the members? Many have experience using social media platforms to collect data.
