It's the path of least resistance. I used to write one blog post per day, but when I switched to a static site generator I only write one blog post per month. The difference was that before I went to my web site, then wrote the content in a plain textarea. Or sometimes I wrote it in a text editor and copy/pasted it into the text area. Now I have 1) open the CMS 2) Create a new page 3) Fill in some meta-data like title, date and description 4) Write the blog post. Before all blog post was on one long page. Now it's one blog per page. So before I was OK with writing a very short message.
