What is the Best Blog Post of All Time?

I am on the hunt for the best blog post of all time. I am compiling a list of the best blog posts of all time and am going to rate them using various methods that define quality, amount of traffic, and overall awesomeness.

I have written in the past about the best time to post a blog post, but now I am searching for the best blog posts of all time. So, please nominate the best blog post of all time, even if it is your own. You can use Twitter or Facebook or the contact form on my web site to get in touch with me.
