This question already has an answer here:
- What is a meta for? 7 answers
In my experience, sharing ideas (which are opinion-based and not really questions by nature) is fine in meta sites. For example:
- Any announcement posts from the staffs. For example, in Net Neutrality and Stack Overflow / Stack Exchange it is specifically said that "if you've got something to add, please do write an answer!"
- Observation posts from regular users. For example: Case Study: First Answer Bias or Technical support: rational vs emotion in Academia Meta
I want to make sure if my understanding is correct, because I have such an idea about Stack Exchange vs Reddit and am quite surprised when it is downvoted and closed.
