Needed: An Open-Protocol System for Commenting on the Web

One thing that many blogs have embraced is the trackback system for blogs to
shout out to other blogs that they’re linking to them or using their information.  This is a
wonderful idea, and a similar solution should be applied to comments.

Now, I’m not fully
up to speed with micro-formats and RDF, and such, but such a system should be easy to create and implement. 
The first thing we should do is extend RSS to include it.  We already have the <comments>
tag, which should obviously link to an RSS feed of comments for the item (using this new system, anyway.) 
So we need to add a <postComment> tag, yes?

This tag could go in either the
<channel> element (for Comment-Streams) or in the <item> element (for
news-streams and/or as a direct reply to other comments).  Lets break it down something like this:

style="border-bottom-style: none; text-align: left; padding-bottom: 0px; line-height: 12pt;
border-right-style: none; background-color: #f4f4f4; padding-left: 0px; width: 100%; padding-right: 0px;
font-family: 'Courier New', courier, monospace; direction: ltr; border-top-style: none;
color: black; font-size: 8pt; border-left-style: none; overflow: visible; padding-top: 0px" id="codeSnippet">

            name="newsID"
            value="12345"
            />

 4: <input             style="color: #ff0000">type="text"
            name="name"
            required="true"
            />

 5: <input             style="color: #ff0000">type="text"
            name="email"
            required="true"
            />

 6: <textarea             style="color: #ff0000">name="comment"
            />
