Have you ever really been lost on the net?

About a month ago my computer crashed at work...I've felt a little "net" lost ever since. I lost all my blogs that I follow, all my email addresses, the list could go on and on. I've stumbled across some of the ones I had saved but for the most part I've lost them. Ugh! It was like 5 yrs worth of blogs, websites, etc. SO apparently I need to make a list offline to stop this from happening again. Do you use a system for saving all of this stuff either online somewhere or just a list offline in general. If so let me know what it is. I'd love to know!
