“Very Mary Kate” is a comedic parody of 1/2 the Olsen’s by a woman whose name I don’t know, acts like……well very much like Mary Kate.
Here is “Mary Kate’s” description of her own blog:

“It’s called “Very Mary-Kate”.  It’s about marine life. Ha! Just kidding.  It’s about me. Follow my twats on tweetspace or whatever. twitter.com/verymarykate. i can’t make it a link so figure it out for yousrelf. prolly just have to cut and paste it into a new tab or something. i mostly don’t use computers much cuz my hand bling chips the keyboard like whoa.”

Whoa.
