Better content discovery:

The latest activity page isn't too far off. If it was filterable, showed all content types and could be ordered as a user chooses, it would be fine. It would also be good if when a user "follows" a node, or content type, you could filter by "content I follow" on latest activity feed. We should be able to create content from this page, and also interact with and reply to existing content.

Additionally, when viewing a media item, say a Space Marine, I should be recommended other Space Marine media items, but also thread posts, article posts, resources, etc as part of the same widget. "Related content" instead of "Related threads".
