You what's really weird...
Whenever I get the urge to spontaneously write an article that I hadn't planned to write, and then I give in to that urge and publish something right away, people always give me feedback that suggests I wrote it for them personally. I.e. "it speaks to me." This happens every time I do that.
But when I write an article that was on my "to blog" list or that I outlined in advance or that I picked at and then edited over a period of days, I almost never get that kind of feedback.
Also, the experience of writing spontaneous articles is very different. I usually feel much more in the flow. I often write much longer, but it seems a lot quicker and easier.
As I'm sure most writers could attest, cranking out a 6,000-word article from initial idea to final editing in 5 hours is very fast. That's like writing a book chapter in an afternoon. When I do a planned piece, an article of that length could easily take 2-3 times as long, and I'd still consider that reasonably fast. For example, "
How to Make Money From Your Blog" (7300 words) took me two solid days (about 15 hours) to write and edit, and that seemed quite reasonable to me at the time.
