Finally. Those annoying Facebook quizes and application stories can be expelled from your news feed forever. A post on Facebook's own fan page says:
Once you see a quiz or annoying story, you can block it right from the feed.
Users can also hide these items in the application's settings page, which is still a hurdle for most people to find.
On the flip side, it also just got easier to create an application. I guess you give and you take.
If you want to use the best version of Facebook though, direct your browser to Facebook Lite. No junk.
