What really strikes me is how technically weak some newly published books are. I'm easily given the impression that there must be quite a few agents and editors out there who are in the business for their love of reading, but have little technical understanding of storytelling.
And by that I mean simple things that would get negative comments in our critiques section - characters who start off bored, or who sit around for chapter upon chapter doing nothing but listen to other people infodump at them.
It's really underlined to me the importance of a writer having a good team behind them, to ensure that they can become as good as possible by themselves, rather than expect that people in the industry will do that for them. Not least because it is so easy to overlook or excuse your own mistakes - until someone that you trust points them out.
