One of the things that Beaker can do in a centralized manner is nudge people in the right directions. Give them ideas for how to actually use Beaker.
One way to do this might be to create a kind of “app store” in the browser. It would basically be like the Templates page in the documentation today, except it would look and feel more like an app store that people are accustomed to using.
The beauty of it is that if someone wants to bypass the official Beaker app store, they simply just don’t submit it to be added. They can still get the same distribution benefits.
