David, how long do you keep FTP download stats and can give us any access to the ones pertaining to XEmacs downloads? Gunnar Evermann <Gunnar.Evermann(a)nats.informatik.uni-hamburg.de&gt; writes in xemacs-beta(a)xemacs.org: The statement is absolutely true under the condition given in the footnote: We don't have any other means of measuring usage. One can take note of platform specific questions going through comp.emacs.xemacs but I don't think that's a particularly reliable measure of usage either. I'm basing my prediction on the rate of change of bug reports per platform and the rate of change of build reports per platform as well as the binary kit download stats from UIUC. All of those metrics show Linux usage increasing exponentially. Given the known volume of Microsoft Windows hosts and the rate at which I've seen the XEmacs on Microsoft project grow, I feel safe in predicting that it will continue to grow quickly. ;; I'm well-aware this can be inaccurate too as some get lax in reporting ;; on systems they are active in testing. ... Neither do I. That's undoubtedly true. How much does it skew the numbers? I don't know. The number is complicated by the fact that many XEmacs users use it on multiple platforms including Linux at home. Do you count them twice? I'm vaguely interested in getting an order of magnitude (or two) count, but not enough to want to invade people's privacy.
