Microblog entry that is viewable not by everyone doesn't show up in the Whats happening portlet
1. From the Home page, add a microblog post viewable by friends
2. Click 'Post'
3. The post isn't visible under What's happening
4. Go to the microblogs page
5. The post is visible
The post will display properly if it was made viewable to everyone. I couldn't reproduce the issue at revision 80627.
