Now that Quora has removed Most Viewed Writers by topic, does it actually matter if question writers bother to spend time editing topics?

It is critical. Topics are how questions are distributed to potential answerers. MVW is a motivator to answer questions (and one that I do not think should have been hidden); but without topics, your questions simply aren’t going to get distributed to those that care to answer them at all.

How do  languages other than English deal with gender-neutral pronouns?

The Swedish gender neutral pronoun hen has a lot of controversy around it, as divergent responses here on Quora show:

So: not necessarily as well as you might think. In fact, English they/them has an advantage over many languages’ attempts at gender-neutral pronouns: there’s linguistic precedent for it (though it was as a non-specific, rather than as a primarily gender-neutral pronoun)

Could someone tell how electric power resembles juice?

The analogy is not with juice as in orange juice, as suggested by Dobhran Black’s answer to Could someone tell how electric power resembles juice?. Clearly there’s an analogy with fluids to be made; but why juice and not water? Or quicksilver?

Or blood?

The analogy is with vital juices, a concept that was kicking around as a literal concept from the ancient Greeks until modern medicine, and that indeed persists even now, both metaphorically, and in reference to plants (to judge from Google Books).

Vital juices encompasses the fluids moving within a living organism, that allow it to keep living. If the vital juices are flowing through the organism, then it does things like grow (if it’s a plant) and move (if it’s an animal).

If there’s electricity flowing through a machine, then it does things that resemble life: it is animated, so to speak. It moves, it whirrs, it does things.

So, the similarity is both the fluidity of electricity, and the vitality it confers.

Are there languages other than Greek, whose speakers refer to situations such as shopping on Black Friday as pilgrimages?

Metaphorical reference to any visit to a prestigious or desirable site as a pilgrimage? Sure, English does that. In fact, right here on Quora:

Why do people (like to) say “I made a pilgrimage to the Apple Store” as if it were Mecca?

Is it true that all mafiosi must make an annual pilgrimage to Las Vegas?

Pratik Bakshi’s answer to What are some amazing facts about Pokémon GO, both as a game and out in the world?: According to reddit ” Playing Pokémon Go in India is almost a pilgrimage.”

With the anglosphere mainstream being either Protestant or Secular, it’s been quite easy for them to use the word more metaphorically these days.

Remind me Chrysovalanti: is the Greek word you’d use προσκύνημα? Because pilgrimage is certainly one of its meanings, but it applies rather more broadly than pilgrimage: it applies to any veneration of relics or saints, and does not require that you travel far. Of course, the veneration of relics is no more Protestant or Secular than a pilgrimage is.
