technically the difference between a social post and a blog post on 10C is just the type and quantity of metadata. They're supposed to appear all together in a stream, hence the project name.

To get the URL of a blog post, copy the link in the browser that is seen after publishing a post. To prevent a publicly-accessible post from appearing in a timeline, you will need to backdate it a bit so it doesn't immediately appear, but there is no publicly-accessible setting to publish without also having it appear in the stream 🤐
