Slowly I find I spend less and less time on the main site and more here

I haven't read the whole new question list for a given day in months

I have seen OrderingBy in the planning notebook in some Twitch streams, but I do not know which livestream it was discussed in. Does anyone understand the point of OrderingBy? Wouldn't OrderingBy[list, f] be the same as Ordering[f /@ list]?

SortBy is genuinely useful (actually very useful), but I do not get OrderingBy.

it could maybe be useful if they also make an operator form: OrderingBy[f] @ list

@kickert, if you're interested in having a gathering of MSE members in the conference, consider making a post on Meta.
