Get yours before there all gone!
Since I have discovered nil about the subject of pinging that I can understand all I can say is there seems to be good things about it, and it can be used harmfully. Like mostly everything, this seems to be the case. Good against evil as usual. I think finding a great site where you might get free blog ping might be a great idea. They might even tell you what it is and why you need it. I think I might just need the “pinging for dummies” book at this point. Seems that is the series I am always buying when I need a “how to” book. I do know at this point, you might want to ask the person with the website offering this service because I sure know nothing about it.
