Quizplus · Accepted Answer

A trackback is a way for blogging systems to communicate with each other. When a blogger writes a new post on their own blog, they can link to an older post on someone else's blog. This link sends a trackback to the other blog, letting them know that their post has been referenced. The trackback will then be displayed on the original post as a list of entries (with links) from other blogs that have referenced it.
