I started writing a blog in 2008. That is also when I got my first Kindle and bought and downloaded my first ebook to read on the Kindle. It wasn't until 2012 that I joined Tweeter.
It was also in 2008 that I began this blog. I write a post each day I am home and not on vacation somewhere.
I wrote yesterday about quotations. I write blog posts and send them out the next day. In the interval between (1) composing, reading aloud to my wife and checking with Google Doc's spell checker and (2) posting and emailing, I often have trouble recalling what I wrote or even what I wrote about. I started wondering what has stuck in my mind. I am confident that I have all sorts of memories but they are difficult to call up on the spot. So, I focused on ebooks I have purchased, blog posts I have made and Tweets I have posted.
I looked them up: I have 2695 ebooks, wrote 3631posts and 4695 Tweets for a total of 11031 listed, checkable items. Naturally, whether I buy or post or tweet or not might very well fit in a Poisson distribution. Those actions: buying, blogging or Tweeting occur in integers, not in fractions. That is a mark of possible good fit to the Poisson, sometimes called the model of rare events. From the first day of blogging to today is 4194 days (look it up or have Excel tell you). 11031 actions over 4194 days gives an average of 2.6 actions a day. A Poisson model with an average of 2.6 looks like this:
So, for instance, the model predicts that 51.8% of the time, I will buy, post or Tweet no more than twice in a day. I thought you might like to know that.
