Three days in, and the conversations at SXSW Interactive 2014 are hot. Did you miss out on any of the biggest conference happenings? See what you might have missed.

Day 3 of SXSW Interactive was a good one for wrestling fans. WWE star John Cena and company dropped in to present “Crushing Second Screen: The Ultimate TV Companion”. The session detailed the revolutionary way the WWE has integrated social media into its brand and revealed an incredible level of responsiveness to fans: "If we're where they are, when they want us to be there - then we've done our job." Some Twitter users even called it one of the smartest panels they’ve seen at SXSW.

Nintendo and Pennzoil teamed up to make some childhood dreams come true this weekend. Twitter users sounded like kids again in anticipation of checking out the Mario Karting Reimagined go-kart track at the Gaming Expo portion of SXSWi. Each kart used RFID chips and a GoPro camera to transform the live-action races into digital footage.
