"Little by little, Linux and open source software is making
its presence felt. As must occasionally happen, such gains must
come at the expense of other technologies... At the top of my
list of early casualties are the Motif graphics library and the
Common Desktop Environment (CDE), which is built on Motif."
"A search on freshmeat for Motif apps turned up a whopping 41
matches, many of which don't actually use Motif -- they just claim
to work like it. Compare this to entire sections of freshmeat
dedicated to hundreds of apps written to the two main graphics
libraries used in Linux, Gtk and Qt."
