While I do (mostly) agree with this article, it fails to mention the #1 reason why I never used it. I couldn't post something on someone else's page. I could post something to my "feed" and they could happen to see it. But I couldn't post something into their "feed" (wall, timeline) where all their friends could see it and then comment on it. It was more like Twitter than Facebook. Maybe I'm wrong, but too me they we…
In fact, that was mentioned:
> Of course, Facebook’s news feed has many of the same design elements that I have described here, including ranking. However, important messages sent directly from one person to another have their own dedicated channel that works more like email, with strictly chronological ordering rather than ranking and with an explicit “mark as read” function. Ranking and algorithms are only used for nonessential postings.
Though I suppose it's ambiguous whether he means someone's Wall/Activity Log or Messenger, I suppose, but I read it as the former.
