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
So much for the model. In a practical implementation sense, the
questions are different, but need to keep the model in mind.
