I don't like Twitter. But the service has its uses. So if you ever have to use the Twitter website and you don't want to view all the garbage they forcefully throw at you, such as Trending and Suggestions for things to follow, here is a really easy way to remove that worthless junk.
If you are running Adblock Plus (and you probably should be), you can simply add these custom filter rules to that add-on's preference configuration:
twitter.com##*.ProfileWTFAndTrendsAnd now suddenly Twitter is significantly less annoying.
