how do you get a message to show up on someones wall on twitter?

Hai
Because that last guys is being an idiot ima explain
Her wall thing is called Timeline. On that you can only see her Tweets and her Re-tweets (When someone shares a tweet with all their followers)
When you sent that mention, you'll see it on your timeline. There's a section called @Mentions. Thats where Hopefully Taylor Swift will see it. If you want to see her mentions, you can search at the top @TaylorSwift and then you'll see all her mentions by latest. Remember she's very busy has a ton of followers so she may or may not see it. If you're new to Twitter I think you should read up a bit: http://support.twitter.com/articles/2155...ng-twitter
Hoped that helped! And welcome to Twitter Land!
