At the end of the year, the Nike+ website gave me a "rundown" that told me how far I'd gone and all kinds of things. It told me that my "best" running day is Saturday. (I disagree, but it's only a computer.)
I want a "postdown" for my blog. I want to know the most common day I post. (Currently: Wednesday, I think.) I want to know how many posts per year, graphed by month, number of words. Whatever the equivalencies to the Nike+ system are, but for blogging.
I'm sure there's a way to program it myself, but I think the effort of doing so is probably more than calculating it by hand. I don't want to think about what that means, other than 'I have other hobbies than programming.' Actually, I'd be more inclined to figure it out for the Nike+ because I really DO want to play with the raw data and make my own graphs about my running. The blogging is way less important to me.
