Wikipedia has already shut down for the next 24 hours in protest of the internet censorship bills that will be voted on next week. Tons of other sites are shutting down for a large portion of the day, and plenty more, Google included, are doing something in protest.
Plenty more information here.
If passed, these bills will likely have a trickle down effect (beyond the intention to stop internet piracy) to wonderful blogs like these who would be responsible for users posting infringing copyrighted content (game highlights, audio commentary, logo usage). If others have more/knowledgable information to add, please do. I just don't see what good can come from censoring the internet.
EDIT: Not my intention to get political (I know it's a no no). Just tyring to be informative if you see crazy things on the internet today and don't know why. Mods feel free to delete if necessary.
