Think of it as a blank canvas where you can post images, links, and text- whatever. You can change the background as well as the privacy settings (Google or not) as well as a comment moderation feature (so you preview the comments prior to appearing on the board). You can embed it or share the link (which you can customize or use the default). You can even sort free form or in a linear format
How about a padlet as an assignment page? You could include the tasks, rubric, and examples. Or use it as I did below to gather feedback. You can use their gallery to see other examples. Please double click below and add your comments!
(PS- Just saw this tweet - nice step by step of padlet- from Mr G online.)
