I found this server called StarCraft and it always has a lot of people on.
There are close to 60 players and they hang out together and talk a lot.
The community also uses discord and they seem pretty active and social.
To get into the discord you add the server to your Minecraft server list and then you copy the link it gives you into discord and join from there.
It feels like a server for people who like playing with others and being part of a group instead of playing alone.
