Ping back feature in blogging

Curious about Pingback function in my blog.

After googling, Pingback is a function implemented in blogging software including WordPress. What wordpress does is when your WordPress site enabled auto pingback, when you make a post, WordPress will ping all the links in your post, whenever the links in your post accept the ping (another WordPress blog), then your post will be linked to that another site where another site get the pingback from you.

Then, the blog author can track whoever reference their posts.
