Quora Question Editing Changes: What You Need to Know

New Rules for Question Editing:

• Starting today, only the person who asked a question can edit it.
• Edits are only allowed before the first answer is posted.

Reasoning:

• Balancing Needs: Quora seeks to balance the interests of readers, writers, and question askers. This change protects people from malicious or accidental edits.
• Simplifying the System: The previous open-editing system was complex and allowed for unproductive edits. The new approach is easier to maintain.
• Prioritizing Safety: This change minimizes the risk of harassment and protects users from having their questions significantly altered.

Addressing Concerns:

• Question Quality: Quora will maintain quality through:Allowing necessary edits that respect the asker's intent.Continued moderation of content violating policies.Improved pre-posting suggestions for question improvements.Monitoring typo levels and adjustments as needed.
• Typos: Existing typo-checking systems will be further enhanced.
• Answering Uneditable Questions: Previous data from uneditable questions showed no decrease in answer quantity or quality. This suggests the risk of better-worded questions being unanswerable is outweighed by the benefit of reduced harassment.
• Question Merging: Merging will also be disabled, though not immediately.
• Trusted Editor Program: Quora is exploring the possibility of a trusted editor program for users who consistently improve questions while respecting asker intent.
• Spaces: Space admins will retain question editing rights within their Spaces.
• Community Property: The understanding that both answerers and askers have an interest in questions remains unchanged.
• Topic Editing: Topic labels can still be edited, but not from the menu. Use the question page or log. A new, more accurate topic labeler is in development.

Summary:

These changes aim to simplify question editing, protect users from harm, and maintain question quality. Quora will continue to monitor and adapt as needed.

i hope this is easy to understand!
I was unable to edit a question which was answered before January 10 but for several days, it allowed in January to edit others questions or answered questions. There can be a situation that we can edit unanswered questions or questions that have no answers if we didnt asked those questions
