I've seen a lot of people complaining about the prevalence of political articles on reddit. I myself have thought, "I would rather not see any more stories about the LATEST OUTRAGE BUSH DEMOCRATS OMG". So I wrote a simple greasemonkey script that checks for the presence of various words in article titles. If it finds one of the words, it calls removeSiteDom to remove it.

If you like politics but never want to see "10 worthless CSS tricks!" again, feel free to edit the word list.
