In a magazine, there are a number of conventions, including pullquotes and sidebars. But online, a number of issues including unknown monitor width and weaker type control make things like sidebars trickier to know how to deal with. When they offer a article online, HBR pulls sidebars out and puts them on to unique pages, called out here as "in this article."
To make sure you do see the sidebar in relation to the appropriate part of the article, they add a second link inline. However, expectations are not clearly set-- what is this? Even knowing the magazine as well as I do, I had to pause and puzzle-- related article? Whatnot? What is the inducement to leave the safety foe one's spot in the article you are reading to wander off for more information. I wonder if a dHTML expando module would work, or a pop-up or even trying to design an actual sidebar....
