I was hoping for citations that i can get a look at with some raw data and potentially a summary of the methodology for sampling. I'm very interested in getting statistically verifable analysis for any usage numbers for any distribution. I'm especially interested in any analysis break down of ubuntu's numbers not lumped in with as a debian aggregate. The last publicly available data I am aware of that even attempts a comparison... is the webserver survey of netcraft: http://news.netcraft.com/archives/2005/03/14/fedora_makes_rapid_progress.html I'm more interested in the raw data than the glowing conclusions. In fact I'm really not thrilled with how fast fedora is growing in that study of webservers. The implication that fedora web servers are going leaps and bounds sort of worries me that hosting companies are choosing fedora without telling customers about the support lifetime. I really didnt expect fedora usage in the web server space to increase as fast as it has. There's a lot of room for interpretation of that data. But sadly its the only comparable raw data with a set sampling methodology that I am aware of. I am of aware of the distrowatch.com polling, but even they don't attempt to claim their poll is an expression of real world userbase stats. At best its "popularity" and they admit the sampling methodology can easily be manipulated by the self-selecting participants. Remember linuxquestions.org poll.. http://www.linuxquestions.org/questions/showthread.php?s=&threadid=272090 what was the best distro of the year? slackware. Not to knock slackware or anything. But that result seems to indicated a very different world order than you are suggesting... and you even site sampling of linuxquestions.org as a credible source. Sorry, but forum activity just can't be used for anything more finer grained than "critical mass" userbase analysis. Also unfortunately ubuntu shows up as an aggregate with other "debian" releases so even in the very narrow scope of web servers I still don't have publicly comparable raw numbers for unbuntu alone. We could very well lump fedora in with rhel and get equally meaningless results similiar to lumping all debian derivatives together. If you have any references to publicly available raw data, I'd absolutely love to see it. Even getting accurate stats of downloads is really tough. Because of mirrored distribution and secondary torrents you have a hard time knowing how many copies are really floating around out there. At best you can get a nice lower-bound to know if you are getting a critical mass of support, but anything beyond that is impossible to do accurately with download stats. -jef
