Does your Twitter account have to meet certain requirements in order for celebrities or other verified accounts to actually see your tweets to them? The reason I ask is because whenever I treat to any of these accounts, none of them ever respond: I don't remember how many times I've tweeted to Frank Oz and he's never responded, but I've also tweeted to Brad Garrett, Tom Bergeron, Jerry Seinfeld, even SS's official Twitter account, and other companies like Kellogg's, and they never respond.
