I remember a bunch of discussions on the merits, or lack thereof, of the "General Reference" close reason. But in the past 5 months or so, I haven't seen a single question closed as such. Maybe there just haven't been any asked or something.
According to the FAQ, the official general reference sites are Wikipedia, IMDB, and ISFDB. What was ultimately decided? There did not seem to be a written consensus on how we were to use this, but maybe one has effectively appeared?
