The writers I've come to most respect acknowledge how little they know. Conversely, the worst writings I've come across are from people who believe they've figured everything out. This is difficult to appropriately balance - engaging writing needs to exude a certain confidence but must avoid hubris. Gravitate towards writers who are clearly avid readers themselves. Drawing inspiration from a variety of references and depths shows they aren't just trying to show off how much they know - they are sharing in their active hunt for learning.
