To give an example of what I'm talking about so I'm not just being all miss-theoretical here, take [@Sophrus]

Right now he's doing a really good job at carving out a room for his character, Nurian, in the party. He's taking the initiative, performing numerous smaller but faster 'social posts' to establish a deeper relation with the rest of the cast, and is not afraid to make his character collide with the rest of the party, possibly even creating conflict. Even if there is something that doesn't directly concern him, he still posts and makes his character/presence/thoughts known :)
