Experimental-clinical psychologists have finally started to capitalise on naturalistic internet data sources for research. For example, recent papers using data from the social news aggregator Reddit (e.g., Hipp et al., 2015), and the social networking site Tumblr (e.g., Cavazos-Rehg et al., 2016).
The AskReddit subreddit is a particularly useful source. Here, hundreds or thousands of people provide answers to single questions. In many cases these data may be difficult to come by through other means.
