Jan. 18, 2012 Philippines saw the blacking of wikipedia in protest to the SOPA (Stop Online Piracy Act) pending at the U.S. Congress.
As a result students were not able to plagiarize er research for ther assignments.
My personal opinion is a world without wikipedia will be a world of challenge as students will be force to go to their school library and research. Online encyclopedias like wikipedia only encourage academic complacency.
I hope to see a renaissance period in education where students would flock to their library opening moth ridden books, borrowing them and talking about it with their friends.
Until that happens, I will be using wikipedia for the time being.
