That we have all become good citizens, backing up all our data. I presume the data recovery firms are all panicking now that all their potebtial customers have backups of everything, and thus no longer need their services.
Not bad to have a global backup ratio of >1:1
Personally I use RAIM (Redundant Array of Instant Messages) to back up all my important notes and communications. It only works as long as all my friends log everything too, of course.
