Recognizing the Work of Reddit’s Moderators: Summer Research Project

Beautiful example of mixed methods research. With all the quantitative data we can harvest today, but diving into participant observation and hoping to find contextualized insights.

Social Media Collective

What does it take to keep online communities going? With over 550,000 public subreddits, many of which are active, the communities on the site rely on ongoing effort by a large number of volunteer moderators. In my research, I’ve made the case that caring for the communities we’re part of is an important kind of digital citizenship.

I had devoted the first half of my presentation to a digression of sorts, talking about how the persistent scarcity of relevant public data still makes it impossible to produce global forecasts of rare political crises—things like coups, insurgencies, regime breakdowns, and mass atrocities—that are as sharp and dynamic as we would like.

The meetup wasn’t the first time I’d heard that suggestion, and I think all of the well-intentioned people who have made it to me have believed that data derived from Twitter would escape or overcome those constraints. In fact, the Twitter stream embodies them. Over the past two decades, technological, economic, and political changes have…
