FWIW - Just to get some bearings I just looked at some sourceforge download statistics for pygeo and for vpython. PyGeo VPython Nov 2006 31 24 Oct 2006 113 144 Sep 2006 112 160 Aug 2006 90 193 Jul 2006 114 132 Jun 2006 133 575 May 2006 120 72 Apr 2006 119 43 Mar 2006 118 62 Feb 2006 110 66 Jan 2006 136 53 Both numbers are meager by many standards, but I am not disappointed in PyGeo's, in that I have purposefully refrained from promoting it an iota for over 3 years, other then discussion of it here, and only here. My thinking is that I will only promote it when it is complete, in the sense of suitable for a general audience, e.g.well-documented, and having its own editing environment as part of the distribution. And that will be when that will be. Since I don't consider there to be any competition for it - it's kind of its own thing - I don't feel under any enormous pressure. But having trouble making sense of the statistics above, since PyGeo requires vpython and the PyGeo site points folks to the vpython download site. In many months there are more downloads of PyGeo than Vpython, which either means that folks are downloading PyGeo without understanding the dependencies, and giving up, or that PyGeo is being downloaded as an add-on to existing Vpython installations. Or that the statistics are unreliable for some other reason that is not apparent. Assuming the statistics are meaningful , it does seem fair to conclude that PyGeo is a very major factor in generating interest in Vpython, to the extent such interest exists. Where I go with that info, not sure. Art
