As someone also doing production Django for a web-app (as opposed to a news/content site) I'm thrilled to see a team committed to posting lessons-learned... but I'm always suspicious of "We're gonna post lots of great stuff here.. you know, soon." So hopefully you start coughing up the content. Looking forward to it :)
It really is a challenge. Maybe you could create a small buffer of articles. The size of the buffer would depend on how often you're going to post, but enough to last you a week or two. Everything in the buffer should be ready to publish so that you can always post something interesting at the intended rate. Even if you're dead-set on posting that thing on Friday, you'll be surprised to learn how hard it can be to find the time and motivation when your servers are melting, a critical bug has been exposed in your software and you're (non-blog-writing) friends come in, swinging two cold beers in each hand.
This is great. I'm always looking for more django resources outside of the excellent docs, but there just doesn't seem to be a ton of up-to-date stuff out there.
Well, code to restore the database from a backup for one. It also seems to track form which server backups were created.
I haven't looked, but it might also, in the spirit of Django, be "database agnostic" and allow you to import data across DBMSs. You'd still need to keep some things like uploaded files in sync though.
This allows me to have a base settings file which the others inherit from, and all settings are tracked in git apart from passwords which are stored in credentials.py.
Unlike some other approaches, installed apps are just defined once (in the base), but apps can be added/removed for each environment.
