At the larp conference Knutpunkt 2014 me and Rasmus Høgdall hosted the session Social Media in Larps, in a combination of presentation and panel. We provided some of examples of how people have been using social media in connections to their larps, both for off-game and in-game use.
Knutepunkt is a Nordic conference for larp and today is your last chance to sign-up for Knutpunkt 2014. The event is will be held in Halmstad, Sweden 3-6 April. Before that there will be several activities during A Week in Gothenburg (AWiG) such as Nordic Larp Talks on Wednesday 2nd April.
I have attended the Knutepunkt-conference since 2008 and I warmly recommend a visit as you the most amazing people from all over the world.
