I can now stop Loud Twitter posts from showing up on my f-list. All I had to do was insert this beautiful little bit of code into the custom CSS box:
And voila, the Tweets and Twits are gone! In case you didn't notice, I sort of loathe and despise Twitter. Mostly because I don't need anything else encouraging people on the 'net with whom I am not closely acquainted in their delusion that I actually care about their grocery lists and dinner plans and the completely non-witty witticisms they think up during the day.
Sorry, internet people. I'm just not that into you.
