I actually don't touch the world file, and just do the 'emerge world -vuDNa' for updates.
From my POV, that is emerge/Portage's job - not mine.

Aside from that, I'm not sure I have ever really run "emerge --depclean", but I also
rarely uninstall anything, but don't install things left or right to try out either, so
typically upgrades are all I need to do.

Having just done a compiler upgrade, I can say that there are roughly 1100 packages (emerge -eav) in world that were recompiled.

I was just contemplating - KDE4 is stable, and I don't see myself running KDE3 again; so why keep it around.
If 'emerge world -vuDNa' will remove it when it gets pushed off the main trunk, then that's probably fine with me - since that seems to not be very far out now.
If not, then I definitely want to remove it now as there is no other reason for keeping it around.

That's the only issue. My only concern is software (e.g. KDevelop) that may not have been updated to KDE4 yet. (Not a fan of KDevelop3; waiting to see how KDevelop4 is going to shape up.)

I do have the disk space on the systems I have KDE3 and KDE4 on; so that's not a concern.
