So in my Django project I have a few different apps, each with their own Models, Views, Templates, etc. What is a good way (the "Django" way) to have these Apps communicate?
A specific example would be a Meetings App which has a model for Meetings, and I have a Home App in which I want to display top 5 Meetings on the home page.
Should the Home App's View just query the Meetings App's Model?
It feels like that is crossing some line and there might be a more de-coupled way to do things like this in Django.

The answer is yes. It's perfectly okay for one application inside your django project to import models from another application. The power of a django project lies in the apps and their interactions. Also make sure that you have utility applications importing models from more generic applications and not the other way.
Django comes with six built-in apps that we can examine.
A project refers to the entire application and all its parts. An app refers to a submodule of the project. It's self-sufficient and not intertwined with the other apps in the project such that, in theory, you could pick it up and plop it down into another project without any modification.
At some point your apps will have to couple in order to get any work done. You can't get around that.

To achieve decoupling as much as possible,
You need to have a Project specific app, that does all the hooking up things between each other.
Using signals from models to create new models in a decoupled apps helps. But doing too much of this, is foolish.
