Hi David
Yes, embedding a notebook in a post is a very efficient way to share your ideas. Steps are the following:-
- Prepare your notebook in the way you want.
- Log in your account on wolframcloud.com
- upload your notebook on the cloud and open it. Check how it looks and make sure everything work as expected as some objects behave differently on the cloud.
- Click on the button "Publish"
