What is your favorite social media app

The unfortunate thing is that the apps are centralized, the most used and the most widespread. But they have that problem (centralized), they all depend on someone and their interests.

I prefer open source and decentralized alternatives, for example Mastodon, Peertube, Pixelfed, Matrix ... etc.

As you said above, unfortunately they are the leaders now, I will not lie that I resort a lot to YouTube for entertainment or education. I hope that later those alternatives have as much traffic and I continue as the ones above
