This is a significant feature, so probably worth discussing with @TheHollidayInn if you are interested in taking it on.

We have already written the backend support for this feature.

The picture below shows several new features we want to build eventually. One idea for the comments interface is in the center.

The "related links" feature is also there. You can see the web version of these features live today.

AMA is also in this picture, but we are not working on AMA yet.
