The Wayback Machine, a massive archive of the worldwide web, enables users to enter a data and go "back in time" to view web pages from the past. GeekPress reports that the Wayback Machine's output has recently been ruled admissable as evidence.

This should give us all pause about what we publish on the web. We can edit entries, we can remove files, but we can't change the past. And we can't count on time to cover our tracks. So anything we put up on the Web, we better be comfortable with. Forever.
