I have been reading the posts and wondering what is so different about a comment. A comment is nothing more than content very much similar to a node.
Well, not quite. There is one very distinct difference that makes a comment very different from nodes as we treat them today. And it's also the one thing that makes it hard to clearly call a comment a first-class object, in a modeling sense. That difference is: * nodes are "new" objects. They "start" or "instantiate" a piece of content. They are independent, typically. * comments are "follow on" objects. They are a "reaction" to a piece of content. They are *always* dependent upon the node to which they refer. So much for the model. In a practical implementation sense, the questions are different, but need to keep the model in mind.
