There are many types of bloggers / writers. We write according to what we are passionate about. If novel writing is your gig, then let those who like it - express their appreciation. If they don't like it, they can just move on and read another blog and upvote that.
if there is a post that is abusive of others, violates code of ethics (if such a thing exist), spammy / scammy, then by all means - please flag it.
Agreed. As mentioned elsewhere, I'm all in favor of flags existing. I don't agree they should be used in this manner.
