I regularly see feature requests on Meta, sometimes with heavily upvoted answers. A feature request is not really a question with an answer since the poster is asking for a feature to be added to the site. How would I write a good answer to a feature request?
As ordinary user, answering a feature request can be done in such cases, in my opinion:
- Suggesting a "tweak" in the request, which still preserve the original idea but with something a bit different. This is useful to prevent many duplicate requests being posted as different questions. Recent example. (Yes, by me. :))
- Suggesting a technical way to implement the request. This can help the team in case they decide to do that is being requested, ans save them some time. Example where it was being done. (not recent)
- Suggesting a workaround/alternative way to achieve the goal of the request, using things that already exist. This is useful since it achieve the goal, without waiting for SE team to do it. Example. (By me. :))
