I'm also unhappy about KA because of there are only a little amount of badges left. In 2016, they used to have like 200 badges displayed on and now some are retired like the 299 million meters per second but NOW THEY HAVE ONLY EXACTLY 59 BADGES! HOW DISAPPOINTING, SAL KHAN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and can you please add new badges so i can like KA again?

Yes I today earned Bristlecone (fun fact, it's around Nov 13). It's fun to earn a badge, but I was actually disappointed, because now you got to the end of the trend and there's no more badges for awarding larger years. I might be leaving KA for the sake of this. Really, this is serious. I really think pausing some other work and adding maybe just a bit of year badges might do some good and pull some people back into KA.

Badges should be added for the 9th and 10th year too.

I could have sworn there used to be a badge for 10 years of membership. I'm a bit disappointed, because I had been looking forward to getting it, and now even though I've been a member for 12 years, I don't have it. :(

I came up with 17 new badge ideas, but they’re still not enough to replace the old ones.

Newer users never got to experience the old badges

Yea there are so many badges i'd love to have but can never earn and i'm not even a new user I've had khan for 5 years...

There should be new badges regarding streaks and levels. (to replace the old clockwork badges)
