What I sense is a real tension between the web as we know it, and the web as it would be. It’s the tension between an existing medium, the printed page, and its child, the web. And it’s time to really understand the relationship between the parent and the child, and to let the child go its own way in the world.
Generally speaking (and ignoring questions of styling, API availability, etc.), an ideal Web annotation pattern follows these principles:
Annotations appear in close visual proximity to the primary content.
Their design neither distracts from nor hides the primary content.
The preceding principles are followed regardless of screen width.

An inglenook, or chimney corner, is a recess that adjoins a fireplace. The inglenook originated as a partially enclosed hearth area, appended to a larger room. The hearth was used for cooking, and its enclosing alcove became a natural place for people seeking warmth to gather. With changes in building design, kitchens became separate rooms, while inglenooks were retained in the living space as intimate warming places, subsidiary spaces within larger rooms.
