I understand about a fifth of this exchange but I'm glad it's here so I can follow links and search on the terminology. I couldn't tell from earlier posts if mod_python was good or bad. The Django book says: "Apache with mod_python currently is the most robust setup for using Django on a production server." Is that true? And if you start small with, say, an online arts magazine for a metropolitan area, then can we easily scale if we become popular? I'm picking Django because it sounds like they did just this with a newspaper site in Lawrence, Kansas. We are thinking of starting with Webfaction and just seeing what happens. All I know is that I like Python and Django and would rather stick with open source. Thanks for the info. rd -- http://mail.python.org/mailman/listinfo/python-list
