What's this?

If you're reading this, you've probably seen these odd links with funny names somewhere on the site and want to know what they're all about. Well, prepare to feel a bit more Net savvy. Those links are what the geeks call "social networks."

Social networking sites allow you to store and share links and pages across the Internet. It's like taking your bookmarks list and being able to see it from any computer.

Even better, social networks allow you to steer friends, relatives, colleagues and pretty much anyone else to the cool stuff you've found, so they have something better to do online than watching the skateboarding squirrel video on YouTube for the thirtieth time. You're making the world a better place.

The only catch is that while all the social networks are free, you do have to register. Each site has a slightly different focus, so take a look through the links and see which service suits you best.
