I think the biggest news people should "care" about are the lowering of standards for copyright lawsuits and making it easier to seize the property of those being investigated for infringement. Not found guilty- just being under investigation.

This law makes it easier for them to file against you, and just the accusation can get your property seized and sold. I'm not happy about this, but if others think it's no big deal, that's up to them to decide.
