Most of you already know what Ping-O-Matic service is. If not, just visit their site here for an explanation about their ping service (errr… I’m not lazy to give my own explanation about Ping-O-Matic. Actually I already wrote it, then Firefox crashed. So it’s all gone, I have to rewrite this post, and no thanks, I don’t want to rewrite my long detail explanation about Ping-O-Matic again…). Wordpress and some other blogging engine, already have build-in function to automatically send notification to Ping-O-Matic everytime we write a new post, so it can send pingback to several ping services.
