I wouldn’t go so far as to not review a celebrity author’s book if I take the time to read it, but I definitely go out of my way to read indie authors and review their books on multiple sites, (if I like it). If the book needs help, I contact the author and suggest such – even though that might not make me popular. If my book needed help, I’d want people to tell me. It doesn’t help anyone if I just lambaste them for poor writing or editing online. Do indie authors listen to my suggestions – I’m guessing not many, but if enough people them them their book needs help, then maybe they will listen. All indie authors benefit when our group as a whole puts better work out there. Yes, it’s competition, but it also helps our reputation as a whole, and that helps everyone!
