- Add colleagues
- Enable the "User - Activity Feed Job" because it was disabled for some reason.
Then when i went to the "My newsfeed" page, i found no feeds still. I didn't get the feeds in my "recent activities" either. After some investigations i found out that the "All Authenticated" users for the Claims provider that the Web Application is using must be added to have read permissions on the social data. You can do this by going to the User Profile Management page and then going to the "Manage User Permissions" page.
After doing this, and then re-running the job. The feeds appeared :)
