Gnome on Slackware has also another option, dropline GNOME, which of course
is not always ready for the last Slackware release, but we are trying our best.
We have nearly ready gnome 2.32 for Slackware 13.1 and soon we plan to
release it for Slackware 13.37 .
Also a great article, stating exactly what Slackware is. I'm a Slackware user from 3.3 version, or maybe earlier... Anyway simplicity and full set of packages is what make it my preference over other distros.
