Oh I love science fiction! PKD's probably my favorite for some reason.
Yeah some people might not consider reading, but it's not a reflection of the quality but rather the length and 'what do I have to gain from it, my comment is not gonna get upvoted by a whale' etc. Plus there's so many things being written, it's hard to get noticed sometimes.
Before I responded to this I wanted to find a copy of the most dreadful rejection letter PKD received. Best I could do was this description of the wall surrounding his desk: "...in a corner of the room above his desk he had glued the many rejection slips he had gotten over the years". A fuller description is here. It's amazing what we would have lost if he'd listened to these critics.
