I'm referring to
Has anyone compiled a list of all of these predictions-come-true?
Now, does this fall under our no-lists rule?
TL;DR: Asking for a resource that contains a list of items isn't, by itself, sufficient reason to close a question under our "list question" policy, but that doesn't automatically exempt it. Rather, it should be evaluated based upon the overall scope and clarity of the requested list (regardless of whether it exists externally to our site).
First, to clarify, I don't believe that we have a strict "no list" rule... rather, we have a rule against open-ended or overly large lists. Limited lists of reasonable scope and focus, on the other hand, seem to be acceptable.
That being said, I think a question asking for a resource that might contain a list is not really that useful, unless the resource in question would be really popular/widely used.
An example of a "good" version of this type of question would be Where can I quickly check if a given X-Files episode is a MOTW or arc episode?. Note that the answer isn't just "click on this link"; it contains the actual relevant episode list.
The Doctor Who question linked above, though, is not what I'd consider one that will be particularly popular or widely used. Changing it to "are there any existing lists" doesn't really fix the fundamental problem; instead, it just makes it possible that the correct answer to the question is "no", which is of no practical use to anyone.
For that reason, I would (and did) downvote the question.
As to whether it should be closed based upon it being a "list" question (albeit one somewhat in disguise), I'm somewhat on the fence. Technically, DVK is right that a list of sites that provide this specific content is reasonably scoped, and limited. However, changing the question from "does anyone have any to add?" to "Is there a resource online or in print that has addressed these events?" seems to me to be trying to get by on a technicality.
Fundamentally, either variation doesn't strike me as a good question.
I agree with it being closed, although I think in its current form, the main reason for it being closed is not necessarily that its a (disguised) list, but rather that it really isn't clear what is being asked. Is the OP looking for predictions made in the show that happened in the real world, outside of the show? Or predictions made in the show that were later shown to come true in the show?
Neither of the two examples in the question are particularly helpful. The UK had apparently been discussing adopting the metric system for over 100 years prior to the first episode of Doctor Who. Within 2 years of the "prediction" airing, a formal policy of metrification was started, but it is entirely possible that there were discussions of the topic at the time the first episode was scripted. Additionally, the UK does not seem to have fully "moved to the metric system" yet, so the "prediction" arguably hasn't come true:
As of 2012, metrication in the United Kingdom remains partial – most of government, industry and commerce use metric units, but imperial units are officially used to specify journey distances, vehicle speeds and the sizes of returnable milk containers, beer and cider glasses and are often used informally to describe body measurements and vehicle fuel economy.
Regarding the "meteor landing in Russia years before it happened"... is it perhaps referring to The Tunguska Event, which occurred almost 60 years prior to the first episode of Doctor Who being aired?
