JEB-LOG

For me, I could not understand TrackBack until I used it. As soon as I used it, I realized it was an alterative way to adding a lengthy comment. (At least that is one obvious use of it.)

Kelly posted an article and enabled the "Allow Pings" option.

This made a "TrackBack (0)" link appear next to the "Comments (0)" link. Clicking on the TrackBack link produces a TrackBack URL that can be copied and pasted into the "Ping" field on my own blog article. By pinging from my article, my blog sends an update to Kelly's blog, incrementing the link to: "TrackBack (1)". Then, others can see I've posted a response, seeing my article title with an excerpt.

Very useful for an exchange of longer articles, giving the responding author the ability to fully edit the response. (Once you've posted a comment, you can't change it.)
