Too much tehcnology

How does one keep up with all the information found on the web? I find such interesting articles, web sites and information, but I don't know what to do with them. Most I happen upon at work while searching for topics about sustainability, how to use Twitter, social networking. Almost always there will be something that catches my eye that I must follow. I get lost in the labyrinth of information. If I find that it's not work related what do I do? I usually send myself an email with the link so I can check it at home. The problem is, I rarely check email at home because I don't want to spend a lot of time on the computer. Is there a book on how to balance life in a technological world?
