> If I leave an annotation with this standard must that annotation be public? Are there options for private annotations? The protocol specifies that annotations are shared over HTTP, you can have them behind whatever kind of locks you want. > How much private data about my browser and my host am I leaving when an annotation is created? The specification doesn't store anything like this. But since everything happens over HTTP, the client/server you use may include things like that. Since it's a standard, you should be able to use whatever programs you wish. There are fields specified to include things like author name, creation date, etc. It will depend on your client how they are used. They aren't required.
