I would love to see the 3D scatter plot of "Time spent by Gentoo users running revdep-rebuild (hrs)" vs. "Package updated" vs. "Date (2000-2010)". I suspect there would be one HUGE blob in June 2010 where "libpng" crosses the X axis. I myself have spent at least an hour on each of the several machines that I run.
