REVISED:
The comment module creates, in effect, a discussion board for each post. When you enable this module, users can post comments to discuss a story, book page, blog post, forum topic, or whatever.

On the USER PERMISSIONS PAGE [link] you can decide which users, role by role, can see comments, post comments, or administer comments, and which users don't need to have their comments first approved. Users to whom you give permission ("administer comments") can decide whether a node they create can have comments or not.

Users can edit the last comment they have posted to a node, assuming no other comments have been posted to it since.

On the COMMENTS ADMINISTRATION PAGE [link] you (or others you empower) can decide, either for individual comments or for many at once, which comments deserve to be published, unpublished, or deleted.

On the COMMENT SETTINGS PAGE [link]

[INDENTED SECTION, WITH BULLET POINTS]

You can tailor the way comments are displayed: newest first or oldest, how many comments on each page, whether comments are shown "expanded" (with their full text) or "collapsed" (only titles and authors shown at first), and whether shown "flat" (all in date order and flush to the left) or "threaded" (comments grouped with their replies). Also, if you'd like, with each set of comments your users will see a control panel that lets them make these choices for themselves.

If you let anonymous users post comments, you can decide whether those users may or may not include their e-mail addresses in comments, or whether they must do so.

You can decide whether users can provide new subject lines for their comments. You can decide whether users must first preview their comments before posting them. And you can decide whether the form for submitting a comment appears on a separate page or below the post (and below any other comments that already exist).

[END OF INDENTED SECTION]

Comments behave like other user submissions. Filters, smileys and HTML that work in nodes will also work with comments.

The comment module provides specific features to inform site members when new comments have been posted.
[MY COMMENT: A vague mention of specific features won't do. What are these features? How do I implement them? Do they work out of the box, or do I need a user-contributed module?]
