This is good, but it's describing blogging as something with a metric for success, and I don't think blogging needs that.
If your purpose with blogging is anything other than to write about stuff you're passionate about, then you should probably start by defining your goal.
Is it to get the largest number of followers you can? Then you can start by looking for the low-hanging fruit - if the medium you've chosen doesn't already have a food fight about vim Vs Emacs, start one!
Is it to improve your chances of getting a particular job? Then you could do better if you research the role and find something to write about which relates to both the company and yourself.
