announces Trackback and Pingback support officially announced support for TrackBank and Pingback links. Search engine optimizers are already excited by the prospect of “anyone linking to a CNET story who sends the proper notification will get a link back in return” from the PageRank 8 site.

CNET is also referencing TrackBack and PingBack URLs as link relations in the page header. I like the TrackBack button for readers CNET uses for readers to look at other related sources.

I need to do some more reading on Pingback, still not sure what differentiates it from TrackBack.
