I’ve recently heard of front page curators and apparently there was a section for projects they chose, but i dont see it and i was wandering if they were discontinued and if so, why?

Maybe they just forgot about it…? I don't think it's discontinued yet tho.

It's not meant to be discontinued but because ST was experiencing problems with the front page the FPC program has been temporarily been paused since September 2024.

It was discontinued, we dont know exactly why.
However the Scratch team has been thinking of “new ways to uplift projects” and that's why trending has been down and what the community is loving, etc. is not available.
I would assume this is also why FPC ended.
