This year, TVGuide.com launched Social Power Rankings to track which TV shows and celebrities our users were talking about. Check out the moments that had everyone buzzing the most in 2011.

"I would like to see Andy Cohen [replace Regis]. Although I'm not a huge fan of his, if he can interrupt and get the interview going with the screeching that goes on with the Real Housewives reunion specials, he can definitely do so with Kelly's constant yammering." — Angie-bella2

"I'm so tired of the 'Moonlighting curse' argument — it is ridiculous. Moonlighting did not go off the rails because Maddie and David got together, but because the writers went utterly mad." — Darbyelsa1

"Len is the same every season. He is a tough judge and always has been. Fair or not, it is what it is. That doesn't give Maks the right to be disrespectful." — Terri LaValle

"There is no network show as ambitious and challenging as Community, in my opinion. [It's] not only funny, but brilliantly structured." — ktharker

"He had me in tears, too (as well as laughing). It was a beautiful and heartfelt tribute that Uncle Frank would've loved. I sure did!" — DeaconGladstone

"I watched these shows with my kids, so I'm feeling the rush of nostalgia, too, and am looking forward to watching them again." — monkey65

"Next season will be the divorce. I bet her mother already selected the divorce attorney." — acoustic622

"Charlie Sheen jokes write themselves." — tvjunkie99

"Wouldn't it have been nice if she waited until a day or two after the awards to announce so the people who won could enjoy the accolades of their work?" — Sweeti6637

Christina Aguilera's National Anthem Fumble at the Super Bowl "Despite the fact that it's a nerve-wracking situation with millions of people watching, if you're going to sing the national anthem, how could you not learn every word!?" — sirlizard

"If a person is a good enough singer/entertainer, they don't need to employ such ridiculous means." — MartieVacek, via Facebook

"I woke up at 2 a.m. to watch this event. As my mom says, this was a once-in-a-lifetime opportunity that is worth being tired for. I know Kate will make an amazing mother, just like Diana." — Katherine Quartermain, via Facebook

"Bottom line: Kutcher cannot act and certainly he will never fill Sheen's shoes. Worst casting choice in years, and it will cost the show millions of viewers. What were they thinking? Unwatchable." — goplad

"Zooey is just adorkable as Jess, and I like the vibe between her and the roommates. Several of my friends want a "douchebag jar" of their own." — ValkyrieX

"We'll miss him a lot. His departure sure was hard on us all. That's what she said." — MikeHafezi, via Facebook
