We need a simple use case to test ping, and see that it works. This is a very simple
one to get started.

And how will Kingsley's server know you are now a member of the group? Unless you ping him, he'd have to crawl the whole internt - an impossible task - to find your file.

Of course you could mail him, but that is not scalable.

The first step in any protocol always seems somewhat artificial. When the first telephone came out it certainly would have been easier to send the same message by pigeon, or mail, or event travel by horse to meet the person on the other end.

Here too, you could mail Kingsley, but we would like to automate it, so that we can test his setup in automatic ways, and in a transparent way.
