There's at least one variation of this in the Suggestions section down at the bottom of the Forum in Everything MDL. It shouldn't be difficult to find its thread.
Something you can do now is make a Custom List (or several, depending on what makes sense for you) and add whatever you want in the Comments for each person . What you've already seen them in, their work you'd like to see, or anything else.
But the conversation around ideas for how to improve the site mostly happens in the Suggestions section. When you find the thread, check how long it's been since it was first made. Which is why I suggested something you can do now =D
