Please ditch the five-minute window on comment editing
Why can a comment only be edited for 5 minutes? If errors cannot be corrected, then the site will remain cluttered. Questions and answers can always be edited and improved. Thus, it would seem reasonable to allow a comment's author to edit comments at any time. However, allowing edits for 30 minutes would allow sufficient time for proofreading and editing.
It would also be nice to have a preview of what the comment it would look like once it is submitted, as with questions and answers.
I do not agree with the Proposal to streamline comment editing, but I think increasing the extremely short time limit would be reasonable. It would not be as complex to implement as the above proposal, yet it could solve a lot of problems. As for "A lot can happen on a new, active question in five minutes", many questions have very little activity, even when they are new, and are lucky if something happens every few hours. Compared to this, five minutes is extremely short.
Such a short time limit is inhibiting for people who are not native English speakers and people with disabilities. Accessibility is a real issue, and I believe increasing the time limit would help many users.
What was the philosophy behind the 5 minute editing limit? Could it be changed to allow more time?
