User home and Desktop folder; position in Places sidebar

[David Siegel <djsiegel ubuntu com>]

In the Nautilus Places sidebar, why are my Home folder and Desktop
folder with the disks, and not with my other bookmarked folders, as they
are in the Places menu? From a user's perspective, these are just
folders containing their stuff. How do we justify this placement to
users?
