SciFi.SE's identity is still being defined, and as such there's a lot of unresolved confusion wrapped up in dozens of topics about what types of questions are acceptable.
Let's stop creating disparate topics that don't get a definitive answer, consolidate our efforts, and use this topic (and this topic only) to propose types of questions that might make the grade here on SciFi.SE so we can discuss and vote on them. This way, we have one single source for what's on-topic and what's not that can be referenced when dealing with concerns about specific questions.
The end result of this exercise should be enough to formulate additions to the FAQ and an end to a lot of the confusion.
- One type of question per answer.
- Provide a brief description of what the type of question is about.
- Provide example questions that would fit the question type.
- Use the comments to discuss why it should or shouldn't be a part of SciFi.SE.
- Vote up answers that you think are on topic, vote down answers you think are off topic.
