Script Summary: Removes Twitter Trends and "who to Follow" from the Sidebar. Works, as of 10/22/11
This Script removes the stupid Twitter Trends and "Who to Follow"-Windows in the sidebar. All the other scripts I tried did not work, so I wrote my own.
Attention: Due to the way twitter is programmed, I had to add a delay of 5 seconds before removing the parts of the homepage, because otherwise they would not have loaded and the removal would fail. Feel free to tweak the number up or down, depending on your connection speed to twitter.
You can find the Delay (in milliseconds) at the end of the source Code (5000 at the moment).
