I absolutely love this ping thing that Dougal and Matt came up with. It saves me an awful lot of bother. My hand-rolled content management system isn't capable of delivering pings to the major services* and I was getting tired of filling in the forms that are available. My only quibble is the fact that it is very slow, but that is probably more to do with the responses than the application itself. I'm surprised there isn't a donate button somewhere.
*Actually, I am too stupid to figure out how to do it.
