From the “using unstable on my desktop” department:

Just two things to point out: liferea-mozilla has been superseded by liferea-xulrunner; so if liferea is held back at your upgrade, do an apt-get install liferea-xulrunner.

The old file manager of XFCE has been replaced with “thunar”. Just do an apt-get install xfce4 to get the latest xfce4 suite. You might want to install the recommends, too.

And remember, don’t just blindly run dist-upgrade. This is meant for upgrading e.g. from woody to sarge. For daily use, upgrade is much better, since it’s less aggressive at uninstalling applications you might miss afterwards. Aptitude may also offer you alternatives in conflict situations.
