This site is not about spoilers, but there are a bunch out there that are. I'll do my best to retweet any good spoilers on my Twitter account @ViewsOnTheAir. But if you're not into tweeting, or you don't appreciate the selection of shows that I cover, take a look at these websites:
Watch With Kristin: Kristin hosts her own segment on E!, but she also has a spoilerchat every Monday where viewers can submit questions about their favorite shows. She also provides videos of interviews from your favorite TV actors. http://www.eonline.com/uberblog/watch_with_kristin/index.html
TVLine.com: For those of you who are fans of Michael Ausiello (formerly of TVGuide and E!), he has launched a new website chock full of spoilers, casting scoop, and more. He continues his Ask Ausiello column where he, like his frenemy Kristin, hosts a spoiler chat. http://www.tvline.com/
