&gt;especially on facebook. each person&#x27;s trending stories could be different and be presented based on what it thinks is popular AND applicable to you.<p>I would agree that this is a fair assumption to make about how it <i>should</i> work.<p>&gt;cuz i get regional stories. im sure my friends in other regions dont get those stories.<p>Yes, that&#x27;s no different than Google News.  That&#x27;s an entirely fair thing to do: tailor a person&#x27;s feed for their preferences and locality.<p>&gt;it is quite obviously targeting me based on something besides a global trending list.<p>Yes, and as long as it&#x27;s <i>unbiased</i>, there&#x27;s no problem with that.  Especially if users can configure it (maybe I&#x27;d really like to see local news items from my hometown, for instance).<p>However, if they&#x27;re intentionally omitting news feed items because <i>they don&#x27;t like them</i>, that&#x27;s wrong.  Omitting news feed items from your feed because you don&#x27;t live in Laramie, Wyoming and these items are only of interest to locals there is one thing; omitting items because they&#x27;re of interest to a political group that you don&#x27;t care for is entirely another.
