Digital Landfill

Do you ever think about how much digital waste there is? I don't mean like electronics, or anything physical. I mean, all of those online diaries, websites you signed up to and used for a week. All the dead blogs, the google docs, the poorly constructed websites long forgotten by the inventions of tomorrow. How many times have you been thinking about all of the times you used to use websites you can no longer remember the names of? Let alone the passwords to access them if you even remembered. It kind of blows my mind how much is out there and yet just sitting in the digital landfill never to be found again.
