Well, the chatbox came up with an odd(ly appealing) idea: Are there enough high-quality sci-fi authors to make an alphabet?
The rules so far: 1. Authors, not writers. Must have published a well-known and well-loved book in Science Fiction. 2. It doesn't have to still be fictional: Prophetic authors like Arthur Clarke and Jules Verne are accepted. 3. Quality: Preference can be given to lasting impact over writing skills, so as an example, Clarke is preferred over Orson Scott Card.
The list so far: A: Isaac Asimov B: Ray Bradbury C: Arthur C. Clarke D: E: Linda Evans F: G: Neil Gaiman H: Robert A. Heinlein I: J: K: L: M: Anne McCaffery N: O: George Orwell P: Terry Pratchett Q: R: S: Mary Shelly T: U: V: Jules Verne W: H. G. Wells X: Can Xue Y: Z:
