Detailed research is all very well, but quite honestly there are times when it would just be a better use of your time to fire off a quick question and get a quick reply from the bounteous well of Helpful People On The Internet. To pay the good deed forward you could give a little of your time to answering the questions of others.
I'm primarily talking about things that can be answered in a flash by someone who knows an area (which could be a literal area or an area of knowledge), but which I would have to spend quite a lot of time delving into to even find out which forum, Stack Exchange or otherwise, would be best place to get an answer.
To illustrate, here are two questions of the sort I mean:
Female pet names that a Londoner might use? - asked on Writing.SE
How to stay true to a Welsh setting - asked in EnglishLanguage.SE
I was very happy to offer answers to both questions, but many people do not approve of this sort of question appearing on StackExchange. One of the questions above was closed, and the other got votes to close. Similar questions on Worldbuilding.StackExchange have had a similar mixed reception.
My main question is whether there is a forum where writers are unquestionably welcome to ask and answer questions of this sort.
(Lurking in the wings I have a potential second question as to whether Writing.StackExchange should be such a forum. But perhaps that would be better asked in meta - and in any case if somewhere else is already open to such questions, there is no need to start a controversy here.)
There are also types of questions that I would like to ask in this "Research Exchange for Writers" forum (if it exists) that would probably be rejected as idea generation here. Things like suggestions for plausible names of characters, places or institutions in foreign countries, requests for little snatches of dialogue in foreign languages, suggestions as to advice on convincing little details to add to the dialogue of characters from backgrounds or places unfamiliar to me.
In the hope of heading off criticism for being slapdash, I would like to emphasize that I'm a great believer in detailed research for the core of your story. However the level of research suggested in this excellent answer would be just too time consuming when all you want to do is have a secondary character throw out a few words about his job or her hometown. For me, spending too much time on that is an addictive temptation I must avoid. This is why I'm looking for a place where I can get answers quickly, if anyone knows of one.
