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.
