When technology evolves faster than law, unanticipated questions on Internet users' rights spring up like weeds. Think of the Electronic Frontier Foundation as a machete for slashing through these digital thorns. Cops want to suck all the data out of your iPhone? Consult the EFF's online consumer guide Know Your Rights. Wondering how that social media site you're addicted to ranks on privacy policies? Check the EFF's Who Has Your Back? campaign. The nonprofit employs a mix of advocacy, education, and litigation to protect consumer privacy and defend Internet free speech. Its lawsuits have countered everything from warrantless wiretapping to the feds' unrestrained zeal in targeting Twitter-ers tied to WikiLeaks. A godsend for geeks, EFF helps you surf safe.
