You can use the Save As Draft feature on blog posts and documents. This can be useful if you need time to marinate your thoughts a little before publishing something. Just create a document or blog post and click Save Draft. Later, when you want to edit it, go to Content > Drafts to see your all your saved drafts. From there, filter your Drafts results by Documents or Blog Posts, find and click on the draft, and then click Edit. You can edit the content and save it again as a draft, or publish it. Drafts are not visible in any streams.
