Tosh often asks questions to his fans and retweets their answers on air. Be sure you want your answer on television before you converse with him. While you’re looking at Swift’s Twitter profile, she may be looking at yours. Swift has always been interactive with her fans, and this includes Twitter. She’s even invited fans to her private home for a screening of her CD. If you ever see a Tweet like this, ask him any question you want. He goes through all the questions he receives and responds to many of them right away. He may respond, and he may not, but either way, you know you didn’t miss your chance! After being insulted by comedian Kathy Griffin, Lovato’s loyal Twitter fans blew up Griffin’s page, sending so many threats that Griffin needed to get the police involved. Lovato stepped in and requested that her fans back off, even after Griffin’s insult. Lovato is a great person to Tweet if you’re just getting the courage to talk to a celebrity. Don’t have a dog? Tweet your animal, regardless of species. Besides renaming animals, he often retweets or responds directly to his followers, so be sure to get in touch, especially if you have anything humorous to add to the conversation.
