Does avoiding criticism help anyone?
This is a very interesting topic, for which I can't come up with a simple answer. The problem is we're all different. My solution was to put in my author profile that I welcome all comments including negative ones. And I really meant it. For one thing, the occasional negative one makes the positive ones more believable. I would like to believe most comments are reasonably honest, otherwise they don't have any value at all. Secondly, it isn't good for readers to always get what they want. As writers, we should sometimes tease them, confound their expectations and generally mess with their brains. Seen from that point of view, a negative comment is a badge of honour.
More generally, I think criticisms should be made very carefully. The LSF is a friendly community and that is worth protecting. It is particularly dangerous criticising someone you don't know, because you're unaware of their mental state and the criticism could be more devastating than it was intended to be. A good policy, which I was taught on some course or other many years ago, is always to pair a negative observation with a positive one.
