There's chilling Internet news out of China. And as bad as it seems at first glance for human rights and privacy advocates, there could be something more disturbing in the wings.

The Chinese government has announced that, starting in July, it will require all computers sold in China to come with Internet blocking software. The goal, authorities say, is to protect children from pornography.

Internet sages are full of rules about stupid things you should never do. But like most recommendations delivered as inviolable laws, the cardinal Don'ts of life online mostly distract you from Do's that would be more rewarding. Here are some don'ts I believe in breaking, and some dos you can undertake once you've let go of these time- and worry-wasters.

Online security and privacy can matter a lot, both to individuals and to organizations. A lapse can mean anything from embarrassment to financial loss... and even physical danger.

But we're living in the social media age, with all sorts of opportunities - and incentives - to disclose even intimate aspects of our personal and professional lives. And when that information gets aggregated, the result can be a surprisingly comprehensive dossier - one far more extensive than we'd ever intended to reveal to the world.
