What you describe seems more akin to why people write diaries rather than write books.

I'm sure I'm over-generalizing but anyone who sets out to write a book has publishing it in mind--and, if they're using a publisher, the publisher certainly does.

Things like blogs blur the boundaries to be sure. But I still view blogs as discrete published items rather than a process I enjoy for sake of the process.

For me, photography is probably more in the enjoying the process camp although I do publish it as well.
