Considering how SO is killing itself rather quickly, it would be interesting to have a platform with similar structure but taking users interests instead of profit of executives. I am not saying their system is perfect, I have made a post in the past on their meta community regarding how hard it is for new contributors to start. I remember hearing about an alternative but after searching for it, I couldn't find anything.

Does anyone know such platform?

Edit: After I posted I came across Codidact. I will try using it! Feel free to post other alternatives though!
