Feel like you have to have the Facebook to keep up with your friends, but really couldn't give a shit about what type of doughnut they are?
Sure, you could go in one by one and block all of the quizzes and polls you don't want to see. But that's a lot of work (especially if you have some of the same friends I do).
For an easy way to block all these quizzes and polls, grab yourself the greasemonkey extension for Firefox (you are using Firefox, right?) Then, restart Firefox and get yourself the Facebook Purity script. Restart, or reload, Facebook, and all those bothersome apps are blocked automagically.
If for some odd reason you feel like torturing yourself, you'll see a little link on Facebook at the top right hand side of the page. It will say:
FB Purity blocked: 3 app msgs [ Show ]
If you really, really need to know what boy band some girl you barely remember from highschool is, just hit the show link and all of the quizzes/polls show back up. Hit it again and you have unbothered bliss.
