Well, these days as you know, copyright discussions are one of the main topics of the media, particularly in Sweden where there is a new copyright law coming soon (July 1) and there recently have been some turbulence (see entry below regarding the raid at an ISP).
One blog I follow closely is Kommenterat.net written by a PhD student by the name of Nicklas Lundblad. The blog is about media and information, but recently the main topic has been copyright issues. It’s very interesting, and I recommend it to everyone (it’s in Swedish though!) I might translate and quote some of his writing here because some is really insightful.
