Pinging merrily away

OK, pinging is working on both this and the Ruby blog. I can really expect the visitors to start pouring in now. Once again, I am amazed by the inability of most technical people to describe anything completely. I wish people who are trying to "document" something would stop for a minute and ask, "If someone really needs this explanation, what are they likely to know?" I now have a long list of bookmarks at Del.icio.us on ping servers, and the vast majority say they are providing an explanation of how to use ping servers, yet say things like "Use this url the same way you would with any other ping server." If I knew how to use other ping servers, why would I be looking at your post on how to use ping servers? The only thing funnier is source code libraries where the author has obviously slaved over his code for years, and yet is unable to even write down the arguments for each method, let alone a single working example.
