Twitter...

I quite like Twitter not because I say anything of importance myself but if you treat them with respect quite often "The Famous" will reply to a question/comment left on their Twitter account(publicly or sent as a PM)and using e-mails or mail is not always easy or suitable.

I have some contact with dj's/presenters that I have followed for many years and even some performers on tv and radio. They get to know who is genuine and are worth responding to.
