Right now user posts are buried beneath the hundreds of "What people are watching" entries. Maybe adding a new tab would be better.
Click on the tab to the right of your arrow that says 'All Activity' and toggle it to 'User Activity'.
That'll allow you to filter what kind of posts you want to see on both the global and following feeds.
Ya, the only thing missing is to remember the setting. The feed stays in the last position you leave it when reloading the page, but activity always resets to all.
This was in the list and is marked as "in progress" right now. Should be in real soon.
