Ask Nicholas Petreley About Linux Usage Statistics

This Slashdot discusssion, about a story Nick wrote, is already going (and heated). I did a NewsForge interview with a SuSE rep who quotes an IDC study that says Linux desktop use will double by 2004. Sounds nice, but how reliable are all these statistics? Nick's been studying Linux use in depth lately, so let's ask him directly what all of these numbers mean, if anything, and how IDC, Evans Data, and other analysts get and massage them. We'll post Nick's answers to 10 of the highest-moderated questions as soon as he gets them back to us.
