I noticed a phenomenon on this blog pretty early on where any references one post would make to another would cause a comment to be created on the referenced post from the referring post.  I didn’t know it at the time, but this is called a ping.  I suspect the immediate source of the term is from the networking command line utility allowing the user to see if a server is alive.  The original source of the term is from the navy (or some water-borne military organization) using SONAR where a sound would be made and a measurement would be taken to determine how long it would take for the sound to echo back.  The sound that was made sounds like tapping a glass, thus the term ping.

To the WordPress world, I’m sure this is all common knowledge.  In any case, I didn’t like seeing this kind of thing.  I like seeing pings from other sites, but not from my own site.  The No Self Pings plugin solves this problem.
