Did you know you can send a trackback to a Yahoo! News article? Just change the domain name to labs.news.yahoo.com from news.yahoo.com (leaving everything else the same), and you will see a trackback link at the bottom of the story.
You can either note the link, or, if you’re using any major blogging software platform, it will be auto-discovered, when you link to a story at labs.news.yahoo.com. The trackbacks show up below the story.
Political items tend to generate quite a discussion.
Update: I stand corrected. Pinging an item at news.yahoo.com would also work, except the pings will show up only on labs.news.yahoo.com
The autodiscovery tags are on the live site too, so blogs referencing any article on news.yahoo.com will work as well.
