What is your take on copyright laws?

As you might be aware that a consortium of publishers namely Oxford University Press, Cambridge Press and Taylor & Francis have initiated legal proceedings against DSE Photocopier (M/S Rameshwari Photocopy Service), on charges of copyright infringement and creating illegal, pirated versions of books.We the students of Delhi University feel this move is another ploy by these wealthy publishers to stifle democratic norms around pedagogy and learning in the University.

In this context, while I was adding a line about copyright I was wondering what sort of copyright laws are applicable to blogging. I am a staunch believer of opensource but what sort of copyright laws govern bloggers.
