A bit of investigative journalism.
Some understanding of Twitter, though a good idea, is not required.
One can always start with Wikipedia...

WATCH FULL SCREEN & HIGH DEF FOR BEST UNDERSTANDING
This is screen capture of live feed of #OccupyWallStreet on Twitter using TweetDeck and Real Time Stream settings. I follow it with several websites explaining what makes a trend and what does not. Although it is a close call and there are factors I am not entirely clear on, it does not appear as if the hashtag behind the revolutionary #OccupyWallStreet is actually being "censored" in any real way - it is not acquiring enough numbers of users, not enough concentration of pace and reach to qualify (but it does appear close if you ask me). With the right strategy, trending is within reach.
From a later tweet from the videographer:
"...I know why it wasn't trending in worldwide now. It has to trend in its region to qualify.
