As much as social media can be a blessing for activists, it can also be their undoing. For a recent example, see how the Tunisian authorities compromised activists' Facebook accounts.

Access Now, an NGO that campaigns for digital freedom, has just launched a handy and concise how-to guide for activists online. It has "tips and tools for reducing surveillance and monitoring, protecting privacy, and dealing with censorship."

Even if you're not an activist, the guide has lots of invaluable online security advice about using HTTPS with email and social networking sites, making smarter passwords, and safely and securely using proxies and anonymizing tools.

The guide is available in English and Arabic, but Brett Solomon, the executive director of Access Now, tells me they've had offers to translate it into 10 languages since they launched -- "everywhere from Tibetan to Russian to Serbian."
