SPOILER ALERT: You don't need to worry about spoilers anymore.
That is if you start browsing the web with the "Unspoiler" extension for Google Chrome. It will block any reference you enter into it. The above screen shot comes from The Washington Post's Entertainment Section after blocking The Walking Dead. Below is a screen shot from Grantland's Hollywood Prospectus blog.
The best part of this extension is that it doesn't work just for TV shows. You could enter anything. Like Katy Perry, or Miley Cyrus, or the most odious, noxious, vile word on the web. Like I did. Here's a Twitter search for the word "Tebow" with the word "Tebow" blocked. It's so much nicer to read.
