Why are there so many blog posts?

When we typed this question into Google, only one page that somewhat answered the question was on the first page of results. According to Leighton Hart, people have blogs in order to have the freedom to write whatever they want, to develop an avenue to earn extra income or promote a business, to help establish a professional presence, or perhaps just as a hobby. 

When Googling the question above within "quotation" marks, the first page that came up is a Facebook post by Nerd Jerk - Inspiring Smiles One Geek at a Time, which states "Why are there so many blog posts to write but NO TIME to write them?! I have like 27 posts backed up in a queue!!!" No answers here. In fact, this more addresses the question "Why aren't there MORE blog posts?" And the general consensus is because we simply do not have the time to write them, or too many other priorities to take care of first. And this is the primary reason we have been silent on the Inkwhy blog for over four months now.

But back to the question, specifically, why are there so many blog posts?

Adding to the motives that Leighton suggests, we theorize that there is a large quantity of people who simply enjoy crafting words and throwing them into cyberspace for anyone (or nobody) to find and read. Blog posts are created  not only when humanity aspires toward freedom and  sustenance, but also when individuals seek power, creativity, connection, self-actualization, or any other number of end goals that could be physical, emotional, tangible or intangible. The number of blog posts will multiply when people find more reasons to create them. And their growth will diminish when we begin discovering other avenues to express our needs and desires.

Do you write blog posts because you don't have anything better to do, because you  have a natural affinity toward writing them, because you have ulterior motives, for a combination of the above reasons, or for some other reason?
