The Social Media Sudoku

I’ve been playing Sudoku a lot on my cell phone recently and being a Social Media lover for a while, I came to an idea to make a Sudoku using the logos of my favorite social media sites such as Digg, Stumble Upon, Facebook and so on.

PS : While searching for the logos I found this cool post by doshdosh, introducing 48 social news websites some of them I had not even heard of!
