I think we all have books in us.
I've read your article and most of the interesting responses below...
Like you, I do enjoy writing. I'm often not satisfied with the results, and may do a re-write later.
I think you are right about it being more difficult to organize a book.
"Have you ever stopped to consider just how much you have written and sent out into the public domain in the course of your Internet "career?""
You may not have meant that literally, but I must respond by saying that publishing in no way invalidates your copyright to things. I believe that you must be quite explicit about your intent to put something "in the public domain."
I am planning to write a "book" right here on Steemit. It will be a series of articles that tell the story of how our grandson was killed by the Medical/Industrial complex with the full support of the state and federal governments and "society" as a whole.
It is indeed a tragic story, one that needs to be told. It is heart-wrenching. It is very personal. I've deferred writing it for many years, and only recently have revived my intention to do so, with a new strategy.
I plan to "anonymize" it in order to avoid destroying some tenuous personal relationships. I hope to serialize here on Steemit. And, while I will do my best to be organized and to produce quality work, as the author / creator of the work, I have no compunctions whatsoever about learning from how it goes here on Steemit, and eventually revising and reorganizing it into what may ultimately be a more cohesive "bound volume" for presentation elsewhere.
Didn't mean to "write a book" here, but your articles tend to elicit longer responses from me quite often. Must be something about your writing! Thanks!

@creatr, thanks for the thoughtful response!
"Public domain;" yes I get that, from the legal angle... more intended as a figure of speech, here.
I wouldn't expect you to remember, but some months back I wrote a piece on authors using Steemit to "serialize" potential books as a viable alternative to trying to get sponsors on a site like Patreon... it got a mixed bag of responses, but it really does make a lot of sense to me. It allows for the building of a targeted "following." You get almost instant feedback... including some that may guide the ongoing development of the book. And you get some "pocket money" as you go along. At the end, you put it all together and offer it as a for-pay "souvenir" (Seth Godin's term, not mine) to your followers... keep a log of everyone who ever comments on the "book" posts and at the end send 0.1 SBD to each with a "thank you for being part of the journey and here's a link to the final book published on Amazon" memo.
Steemit's own @ericvancewalton has already blazed that trail with one of his books... seems it has worked pretty well for him.
Thanks for the kind words, btw... that means something to me and gives me a small measure of hope that "engaging content" is worth the effort!
I thought your "public domain" comment was probably parabolic, but now I'm certain... ;)
Depending on the book, the topic, and the magic pixie dust called "virality," Amazon books seem to range anywhere from total flops to raging, life-changing successes... A couple of cases in point would be "The Martian" by Andy Weir, and "Wool" by Hugh Howey.
So, when will you begin writing your book? That's the problem with interacting here on Steemit; you loose pretexts and excuses when you start to expose your thoughts and intentions... You know, peer pressure starts to kick in? ;) :P
