It's really annoying that almost all facebook launches have/had a delay - e.g. weeks ago the chat and now the redesign and the start of the payment platform is postponed as well...
The newsfeed is annoying anyway. I often got surprised that something landed on the News Feed which supposed should not.
I also had to recognize that Mini-Feed and News-Feed do not hang together and stories show up in the News Feed although they don't show up in my own Mini-Feed.
At the moment you can not control the News Feed properly - this is really scary.
I would suggest a full list of stories, in which you can make settings for Mini-Feed and News Feed seperately.
By the way, there is another bug:
If you click on privacy > NewsFeed and Mini-Feed and unklick "Show comments on discussion boards", they still show up in the News Feed - at least if you write a comment on the facebook page.
I am thankful for all stories on allfacebook, concerning stories about the very bad privacy settings (especially the News Feed).
