Butch Hartman has a Tumblr! The man responsible for The Fairly Oddparents, Danny Phantom, and a great portion of your childhood entertainment, is blogging. If you want to get all nostalgic about Timmy, Wanda and Cosmo, he's got you covered with gifs, early animatics and even a Dinkelberg meme here and there.
Plus he updates on his new project, The Noog Network, an app for kids with games, cartoons and shows. Might be worth a peek at the app store.
