I'm not trying to recruit XFCE users, at least. :) I had never even touched XFCE until about 4 months ago, and only did that because GNOME 3 simply did not work for my needs.
I will attempt to recruit XFCE _developers_ out of anyone who says that forking or contributing "fixes" to GNOME is a good idea, though. Yes, people can contribute to the "Fallback Mode" components, and if you believe that's a better use of your time so be it, but I at least would not contribute to code bases that exist in spite of rather than because of the project's vision. (As in, if Mutter/gnome-panel had the foresight to use a toolkit that didn't demand hardware accelerated GL drivers or if the GNOME predictions about Linux graphics drivers had come true, there wouldn't even be a Fallback Mode; it exists as an official part of GNOME out of necessity, not out of desire.)
