The source for the StackGeek website has now been uploaded to Github. Fork the project if you are interested in deploying your own multi-user Github content based blogging site on AppEngine.
It's worth mentioning that with the site I'm trying to introduce a new pattern for technical blogging and sharing of articles. The site is designed from the ground up to be 100% Open Source and at the same time give authors complete control over their content. Everyone should be aware all content authored on StackGeek is, by default, licensed under the share-alike Creative Commons license. Remember, even under a CC license, authors always retain copyright on their content. StackGeek takes no ownership rights in content created here on the site.
Google AppEngine Boilerplate
Using the Code
Getting the code going locally isn't hard. Check the site out from Github, fire up the Google AppEngine Launcher, and add an existing project pointing to the code you check out. Edit the config.py file and stick in your own keys/hashes/salts/etc where needed.
Fire up the project by clicking 'run' in Launcher, then click browse. Create an account by going to sign up, and then ignore the part where it emails you. You'll be able to enter a user/pass for the first account and be automatically logged in.
If you have any questions, comments, feature requests, bugs you've spotted, or whatever, just open a ticket!
