The SOPA blackout yesterday - it was about piracy on the internet, right? Well yes and no.
If SOPA passes, then it will be illegal not only to host illegal content (e.g. songs) but to link to them. And it's not just in the US - they want to censor everyone in the world.
So, that wedding video of yours where you're dancing to your favourite tune for example? If you post a link to your youtube video of it on mumsnet, not only will you be committing copyright infringement, so will youtube, and mumsnet too for linking to it.
You, youtube and mumsnet will be committing a crime under US law
Under these new laws they will have the power to effectively switch off mumsnet, extradite and jail or fine you, the owners of mumsnet and youtube.
(If you think this won't happen, see this [[http://www.chad.co.uk/news/local/alfreton/bolsover_mum_calls_on_government_to_step_in_after_son_loses_extradition_battle_to_united_states_1_4151073 23 year old student extradited to US and facing up to 10 years because he made a website - legal under UK law - which ^linked( to material which was infringing copyright

The US government will see mumsnet as coming under US law - as mumsnet has a .com address, it's american as far as they're concerned.
If the website breaking their law is outside of the US, then they will still have the power to effectively shut down the site - even if what the site is doing is legal its own country. The law also prohibits the website owners from suing - e.g. for having their business destroyed - even if found innocent! (There's loads of room for abuse for commercial gain by rival companies here).
If passed what this will mean in practice is that it's just too risky to run websites which have user-generated content.
Youtube, Flickr, Facebook, Twitter are obvious examples, and sites like mumsnet too.
It will destroy the internet as we know it.
Why are they doing it? The sponsors of the bill include many large media companies. They basically want to turn the internet into a media channel, where they can broadcast to us. There's a huge amount of money at stake here for them.
