There have been 3 or 4 links about this, each with its own set of comments. It would be nice if various submitted links on the same topic could be grouped together, with a shared comment space. Otherwise, each time a new link of relevance to a preexisting topic comes up, there's a separate page for it, with a separate set of comments.
