That’s not exactly true. Your default feed only shows tweets from accounts you’ve chosen to follow, plus (I think) anyone who specifically mentions @you. That’s why high-profile accounts are subject to abuse and harassment. I guess the assumption is that a public figure using Twitter to connect with fans wants to hear from them.
(Is anyone else surprised that Sinead O’Connor gave an interview to the Daily Mail?)
EDIT: Now that I think about it I might be wrong – you might see replies to your tweets from people you don’t follow. My account is protected, so I’m not sure.
