I also found out about a website that has various posts by pro writers (such as David Morrell) about the publishing industry. It’s called Backspace – The Writer’s Place.
Another great resource is the NINC blog. Members of NINC have to be multi-published in order to join, so I find the information and blogs professional in tone and attitude.
Also, there’s Bob Mayer’s blog. He has 20 years of experience as a fiction writer in traditional publishing, and 2 years of experience doing indie publishing, so I find his posts have a lot of depth to them.
