The next panel at the Digital Methods conference begins with a panel by Theresa Sauter and me, on the viral distribution of links to the video of Julia Gillard's "misogyny" speech in 2012 as it was posted in full on the ABC News site. Unfortunately the audio recording didn't work out, so below are the slides only - do make sure you click on the links to see the video and the animations of the emerging retweet network.

After the “Compromised Data” symposium in Toronto I’ve made my way over to Europe, where my first stop is a PhD symposium in Copenhagen where I’ve been invited to present an update on my work on produsage. Here, I’ve revisited the fundamental concept of produsage and made the link to my current work on the uses of social media, especially in a journalistic context. Slides and audio below:

The next "Compromised Data" is Mariluz Sánchez, who is taking a socio-semiotic approach to the intersection between television and the Internet. This transforms the concept of interactivity, revolutionising reception and enabling the development of transmedia storytelling where viewers develop relationships with the content through various platforms.

Various resources are available to viewers online, promoting consumption and building loyalty towards the programming. Industry is now providing direct access to audiences, and viewers' ability to provide direct feedback can be seen as a form so social empowerment. Mariluz analysed these resources by examining the resources listed on the first five …

The next speaker at "Compromised Data" is Robert Gehl, whose interest is in critically reverse-engineering social media as a form of critiquing and producing alternatives to current social media platforms. This builds on reverse-engineering approaches in engineering, economics and law, on science and technology as well as software studies, and on critical humanism.

Reverse-engineering is a method of producing knowledge by dissociating human-made artefacts. Such knowledge is then used to produce new associated artefacts that bear some relation to the old. Some reverse-engineering has merely functional and pragmatic reasons, but in other cases reverse-engineering takes a more critical …

The final speaker on this first day of "Compromised Data" is Sidneyeve Matrix, who shifts our focus towards geosocial information as generated by smartphones and other mobile devices. Only 12% of US users as surveyed by the Pew Centre posted Foursquare check-ins in 2013, for example, down from 18% in 2011 - but this may mask a greater take-up of other location-based services, not least the Frequent Locations functionality in iOS7.

There is a continuing trend towards the consumerisation of geodata. Geosocial cultural arrangements are explored through the use of mobile communication patterns, but such analysis is notoriously …

The next speaker at "Compromised Data" is Joanna Redden, whose interest is in government uses of 'big data', especially in Canada. There's a great deal of hype surrounding 'big data' in government at the moment, which needs to be explored from a critical perspective; the data rush has been compared to the gold rush, with similarly utopian claims - here especially around the ability for 'big data' to support decision-making and democratic engagement, and the contribution 'big data'-enabled industries can make to the GDP.

But how are 'big data' actually being used in government contexts? New tools and …
