This is an answer to a question I saw on HN a while back: what is the easiest way to put HTML on the web.

The way it works is that you can go to any URL on the domain, be presented with an empty editable HTML page that you can modify as you want. There are some small conveniences made to formatting and has support for drag and dropping images.

It is based on the functionality provided by htlm.org with a couple of improvements (besides no intrusive Javascript). The main one is the fact that a page can be protected by a password forbidding others from editing it. Another one is that you can create namespaces for your notes, by allowing a / terminated URL to function as an index for the pages that exist under it. (You can see an example at https://original.littr.me/~marius/).
