While it’s not required to enter a trackback when citing another post, it’s considered good “netiquette” to do so.
Trackbacks are used primarily for easier communication between blogs.
Akismet is a distributed effort to stop comment and trackback spam by using the collective input of everyone using the service.
After her appearance on a telethon, the number of accesses to her blog increased, leading to continual trackback spamming.
Trackback requires both sites to be trackback-enabled in order to establish this communication.
Pingback and trackback allow one blog to notify another blog, creating an inter-blog conversation.
