That's just you assuming that his face and his post are equally emotional. I could be rolling on the floor laughing (or "ROFL") while writing this post and YOU'D NEVER KNOW. unless you're spying on me. so before i think about that too much, back to the topic!
I think that massive amounts of usernotes involve as much of you posting in them as getting other people to post in them. Which means you need to do a lot of work. Are you up to the challenge?
