That depends on whether or not you plan on sending me hostile emails or PM's because of my choice of star ratings. I can see down sides on both sides of the issue which is partly why I rate so few things with stars at all. If I wanted PM responses to my opinions on someone's work I'd leave a comment that they could reply to. The way I see it if I give a star at all it means I considered your work good enough to view and rate. If I give no star after viewing then you should worry about what I really think of your work.

That itself is an opinion and I don't happen to share it. As I've already stated, any stars on my work whether it be 1 or 5 means someone thought enough of my work to rate it and that is how I view the star ratings.
