Takeaways:
• Schedule multiple posts in advance
• Schedule any post type (text, image, pdf, video)
• You can mention people and companies (something not possible via other scheduling apps, like Buffer or Hootsuite)
• You can schedule between 1.5 hours and 3 months in advance
• You can manage your scheduled posts from the same screen where you write posts.
• Since AuthoredIn integrates straight into LinkedIn, we should be able to support native LinkedIn scheduling straight out of the gate.

What seems to be missing?
• Without AuthoredIn, you can still only have one draft
• You cannot edit a post after it is scheduled
• You can not schedule posts for pages (that is probably coming later)
