It really depends on your audience. I find that the American West Coast, after dinner, or right after school, is when I get the most views, but in the mornings is when I get actual feedback.
Of course, no one ever bothers rating books anymore, so I am personally getting disillusioned with he lazy %%%%% that read online. I just post 'em here to hopefully get a modicum of feedback before I do my final re-write and put them on Amazon. At least there, the appreciation is obvious. Here? Few people bother to even expend the two seconds of effort to push a rating button after you have entertained them for a solid week.
