I don't know if you've ever come across the Open Rights Group, but after seeing a talk by @peterbradwell at the Reading Geek Night I joined up. I think they do some very important work when it comes to public information and citizen activism, but depending on how our careers pan out once we've graduated, a lot of what they discuss in terms of copyright law, government policy etc. could have a real impact on our jobs.
I'm going to their conference tomorrow, and looking at the programme there are quite a few sessions which relate to what we're being taught here. If anyone's interested I'll post some thoughts here after the event.
