Script Summary: Filters keywords from the Twitter discussions you follow
Ever find yourself annoyed by frequent talk of elections, memes and kitty-cats on Twitter? Apply this user script to your Twitter fluid instance or Greasemonkey install to enable regex whitelists and blacklists for filtering out tweets in your Twitter stream.
With this script installed, you will see whitelist and blacklist entry fields at the bottom of your sidebar:
The filter only applies to twitter.com/home* URL's, so you will always see the entirety of a user's tweets when visiting her homepage or browsing elsewhere within Twitter. As long as cookies are retained, the filter will remember your selections. Change your selection and hit enter or click away from the field to see immediate updates to your Tweet filtering.
