The final presentation for AoIR 2015 is by Dayna Chatman and Kevin Driscoll, whose focus is on the communities and modes of social TV engagement with specific television texts. Their focus here is especially also on "black Twitter", a particular subset of the US Twitter population that has emerged in recent years: black American users on Twitter have been identified as a distinct group.

But black Twitter is actually a discursive phenomenon that is driven predominantly but not exclusively by black users in the US. The existence of this black Twitter community was detected especially through Twitter's trending topics, whose underlying algorithms were by accident especially well suited to detect the themes emerging from black Twitter, while "white Twitter" topics were not as prominently features.

The next speaker in our AoIR 2015 panel is Jonathon Hutchinson, who zooms in to a specific transmedia programme screened by the Australian Broadcasting Corporation, #7DaysLater. The premise of the show is to create comedy programming within seven days, and to incorporate social media engagement practices into the show.

Such viewing is more than just subsequent watercooler discussions – it's about viewer co-creation practices. The challenge is to break through the noise barrier on social media, and to find the techniques for encouraging audience participation, especially in the context of a public service broadcaster.

I was the next presenter at AoIR 2015, exploring network-based methods for understanding television audiences on Twitter. Below are our slides:

The final AoIR 2015 session is our panel on social television, and starts with a co-authored paper presented by Darryl Woodford (slides to follow soon below).

Darryl begins by noting that raw social media engagement numbers for television are useful only to an extent: they are usually not normalised to account for specific factors, and simply offer raw quantities.

Nielsen SocialGuide's Twitter engagement statistics for social media follow that pattern, for example, and obviously shows on major TV channels do better than those on niche cable channels. Beamly's social media rankings are skewed by the Twitter terms they track: any tweet containing the letters 'yr' is counted as engagement with The Young and the Restless, for example, which is obviously wrong.

The final speaker in this AoIR 2015 session is Gabriela Richard, whose interest is in female gaming clans. She conducted an ethnographic study of the PMS Clan as well as interviews with gamers.

Overall, there are three waves of female gaming. The first wave identified gender difference in desire, interests, and playing styles; the second expanded the market to develop more female-oriented games; and the third explores more intersectionality between female and other identities (culture, race, sexuality, ...).

The next speaker at AoIR 2015 is Michael Stevenson, whose focus is on what he calls new media "rupture-talk". The idea here is to take what we often refer to as "mere talk" more seriously. Michael points to John Perry Barlow's "Declaration of the Independence of Cyberspace" as an example of this – new media as a radical break from the past.

The concept of cyberspace has been on the decline since its heyday in the mid-1990s, even in major booster publications like Wired. But other rupture-talk concepts, such as MOOCs or the "social graph" have emerged, and are also used to signify a radical break from the immediate past. Such terms are often understandably criticised as hype (Evgeny Morozov's The Net Delusion is an obvious example).

This final morning at AoIR 2015 opens with my paper with Darryl Woodford and Troy Sadkowsky which explores the global Twitter userbase. Our slides are below:
