A New Map of the Australian Twittersphere

Together with some of my colleagues from the QUT Digital Media Research Centre, I’ve just released a new, detailed analysis of the structure of the Australian Twittersphere. Covering some 3.72 million Australian Twitter accounts, the 167 million follower/followee connections between them, and the 118 million tweets posted by these accounts during the first quarter of 2017, the new article with Brenda Moon, Felix Münch, and Troy Sadkowsky, published in December 2017 in the open-access journal Social Media + Society, maps the structure of the best-connected core of the Australian Twittersphere network:

The Australian Twittersphere in 2016: Mapping the Follower/Followee Network

Twitter is now a key platform for public communication between a diverse range of participants, but the overall shape of the communication network it provides remains largely unknown. This article provides a detailed overview of the network structure of the Australian Twittersphere and identifies the thematic drivers of the key clusters within the network. We identify some 3.72 million Australian Twitter accounts and map the follower/followee connections between the 255,000 most connected accounts; we utilize community detection algorithms to identify the major clusters within this network and examine their account populations to identify their constitutive themes; we examine account creation dates and reconstruct a timeline for the Twitter adoption process among different communities; and we examine lifetime and recent tweeting patterns to determine the historically and currently most active clusters in the network. In combination, this offers the first rigorous and comprehensive study of the network structure of an entire national Twittersphere.

I published a preview of some of the study’s key findings in The Conversation in May 2017. Meanwhile, my paper at the Future of Journalism conference in Cardiff in September 2017 built on this new Twittersphere map to test for the existence of echo chambers and filter bubbles in Australian Twitter – and found little evidence to support the thesis:

Some Talks in Oslo ahead of AoIR 2016 in Berlin

I’m on my way to Berlin for this year’s Association of Internet Researchers conference, which will be one of our biggest yet – but on my way I’ve also swung by Oslo to visit my colleagues in the Social Media and Agenda-Setting in Election Campaigns (SAC) project which is now coming to its conclusion. While there I gave a couple of invited talks on my recent research – and the slides from those presentations are now available here.

First, I visited Anders Larsson at Westerdals Oslo School of Arts, Communication and Technology, where I outlined my thoughts on what I’ve started to call the second wave of citizen journalism, now taking place through social media. This essentially provides an overview of the key themes in Gatewatching Revisited – the update to my 2005 Gatewatching book which I’m currently writing:

Axel Bruns. “How the Person in the Street Became a Journalist: Social Media and the Second Wave of Citizen Journalism.” Invited presentation at Westerdals Oslo School of Arts, Communication and Technology, Oslo, 27 Sep. 2016.

Intersections between Follower and @mention Networks in the Australian Twittersphere

The next paper in this Social Media and Society session is by my QUT colleague Brenda Moon and me. Our work-in-progress presentation explores how we can connect our long-term data on the structures of follower networks in the Australian Twittersphere with shorter-term comprehensive information on actual posting activity; we are interested how follower networks and @mention networks cross-influence each other. What emerges already from our preliminary work is that different communities of Australian Twitter users appear to exhibit some very different activity patterns, and that some appear more likely to break out of their follower/followee network clusters than others. One of the newer Twitter communities in Australia, teen users, seem to tweet particularly differently from the others.
