Up and Down Voting for challenges (once they are online)

[doniks]

What would you like to see?

An up or down vote for challenges.

Ideally with optional detailed feedback categories, such as:

• Instructions are clear
• Challenge is interesting
• Imagery is suitable

Maybe also other aspects that are not so much good/bad, but informative to other users

• It takes me 1/5/15/30/more minutes to solve
• It's easy/challenging

Why is this useful?

1. Users can find high quality challenges more easily

2. Challenge creators get feedback on (which aspect) of their challenge is liked/disliked

Additional context

a few related concepts:

• users can favorite a challenge - need to make sure to not confuse users between favorite vs up/down vote, but I think like vs subscribe is a pattern that users are used to on many platforms
• I see that some challenges are marked as "popular" so it seems there is some existing scoring algorithm, maybe based on participation? Or maybe on number of users making it a favorite? Assuming the user voting would turn into the single most prominent score then the existing popularity score could be moved into the list of detailed scores
• There is an issue about voting before going live Voting for new tasks/challenges before they get online #2564 I thought it makes sense to have a separate discussion about the merits of voting after go live, in order not to muddy the discussion. However, maybe it would be useful if the actual implementation of voting would cover both use cases (... or maybe not?!)
