He would make friendslocked posts about being gay and complain about having no money. ^^ And post random meme results and stuff. [...]
Tchaikovsky would have the flocked gay posts and "I'M GOING TO GO KILL MYSELF NOW, BYE" posts.
Liszt would be a total camwhore. Well, he probably wouldn't, but he would be justified if he was.
Beethoven would troll the Deaf comms.
Schoenberg would make posts consisting of letters determined through mathematical formulas and be like "IT IS TOO A POST, BITCH."
Mozart would post fart jokes, of course.
Schumann would have multiple LJs (eusebius and florestan.)
Mahler would be all "YOU JUST HATE ME CAUSE I'M JEWISH" alternated with "ahhhh death omg omg!" posts.
And then the thread goes on to Les Miserables journals and just gets funnier...
