SeaWorld's Shamu is on Twitter. You can follow Shamu on Twitter at @RealShamu
. Shamu's bio says "I live at SeaWorld. I'm a large, athletic, black and white marine mammal. I'm not THE star of SeaWorld, I'm A star of SeaWorld." A real person is behind the Shamu Twitter just like a real person was behind the Mars Phoenix
Twitter that was very popular last year.
When blogging starting getting more commercial several years ago there were many character blogs
