Yes, most of the current web users not only read it, but also write to it. And if they wrote separate self-sufficient articles and notes, this topic would simply not have been born. And users are inclined to discuss. For example: “In response to your“ nya ”I express my“ fe ”to you >>.
Ie, as a rule, behind each primary material (which may be an article or the first message on the forum), there is a “tail” from the discussions, a long tail ...
Basically, I saw only two organizations of comments: a tape and a tree.
Examples of tapes can be forums on YaBB, PhpBB, well-known site “Membrane”, etc.
Examples of trees are Habr, LJ and something else.
In this and in another case, a big discussion turns into a natural disaster.
Immediately I will warn you, I do not know the solution to the problems that I will now raise.
1. Ribbon trouble
a) The message itself does not have a graphic connection with the message to which it is the answer. Therefore, pieces are inserted into the message, or the whole quoted message. This increases the size of the text material, and does not save at all in case of lengthy discussions.
b) And if there are a lot of messages, like on the Membrane, then it is simply impossible to “enter” the discussion from the middle, because 20 pages of messages have been written by other users yet. As a result, the newcomers stupidly go to the last page and write what someone has already said 10 times.

2. The trouble is treelike.
a) Limited "nesting." If an intense dialogue is established between two or three separate people, the message blocks begin to flatten out on the right edge of the monitor, first simply stretching the page and making the text unreadable and then unreadable in general.
b) The lack of opportunity during intensive conversation to track which message is the answer to which one, if the original message went up off the screen. In the case of Habr, for example, you have to attach a ruler to the screen and thus determine the nesting level, then scroll up and look for the message - the parent.
Now the question. Who knows the method, or saw, or he himself realized the principle of convenient organization of unpredictably large discussions, which should first of all be readable?
