I have heard all through some of the forum post that a writer writes for himself and nobody else.
Again, writers write what motivates them, but what some playbook tells them to. It's not a question of what he writes, but whether he believes in his writing and takes any pride in it. Like I said, it's a 'red-flag' issue. If an author doesn't care about his own story, I assume I should care about it either.
I won't criticize any author for his choice of genre, story, topic, characters, style or voice. But if he writes the same thing, over and over, with little regard for what works and what doesn't, it boils down to mental masturbation. No one really wants to watch some old guy masturbating in public!
Writing is personal for us because we form a personal relationship with our readers, even if we never talk. They like our stories because they enjoy the types of stories that we do, they trust us to continue with the things we've done in the past (consistent styles), and hopefully we'll build our readerships over time. Readers learn to trust us because we take such pride in our work, and it shows.
If you enjoy his stories, I don't object. Heck, I used to always download stories and edit them (correcting typos as I went) so they were easier to read. For me, it's more a question of confidence in an author.
