Does Yahoo have a top contributed for every category?

The only two  I know that don't........are Polls and Surveys,   and Jokes & Riddles.   You could NOT earn a TC Badge in those two categories,  but you could still  make the category Leaderboards,   (as it just so happens, I am on both)  I have TC badges,  or crowns--as they later became)  in,   Politics,  Movies, and right here, in Yahoo Answers. 

But that entire system no longer works and Crowns, and Badges were frozen in place when the format changed, some time ago. 

No, not for all SUBcategories, as some have little to no activity, therefore there can't be a 'top' contributor (or in some cases, no contributors at all).

Yes. Jokes & Riddles and Polls & Surveys are the only categories where a TC badge aren't issued.

No, there are 3 categories that never had any top-contributer

Jokes and riddles

polls and surveys

and another one

I can remember getting a TC badge at one time,I think it was in this Yahoo Answers category but they soon took it away !  I once had quite a bit to do with a senior American lady who was on a lot. That is why I was on that category so much before I went mostly to Current Events. Look out for comments starting again next week after Donald wins again (hopefully)

Most them Yes there are a Few that dont have one Like Polls and Survey's
