Ha ha, no, silly Brayn! Web 2.0 doesn't mean sensible retention and backup policies, it means that content is secondary or tertiary to presentation, so it doesn't matter what they save! Why would you care about something like being able to locate old data when there's shiny gradients and colorful CSS boxes to look at and Javascript menus to play with? That's old data, eww! Try some of the shiny new data, it's much newer!
...not that I have an opinion or anything.
