I [mentioned][1] OneNote’s Feed and how it had been obscured in OneNote’s GUI in favor of the Sticky Notes menu. A helpful Redditor mentioned that you could bring the Feed back by:

1. Searching for the Feed in the the Search bar (alt-Q)
2. Type “feed” in the Search box
3. Right-click on the “Open Feed” item in the resulting picklist
4. Choose “Add to Quick Access Toolbar”

Voila! The Feed will be in the upper-left hand of the application’s menu.

Here’s a quick video I made to illustrate.
