- Create a new blogs entry
- Set the display date to the future (lets say 1 week)
- View your activity feed. Nothing should show up.
(this part is important: since its in the future, it will change the SocialActivitySet modified date to that time)
- Now change the display date to the current time or the past.
- View your activity feed again. This time it will show up at the top.
- Add any other type of activity
The new activity will show up below the blogs activity entry even though it happened afterwards. All new activities will continue to show up below it until the original display date (1 week from now)
