It can't be denied that Twitter has completely redefined the relationship between performers and their fans. Once upon a time, our glitterati were untouchable and infallible. Nowadays, one is likely to receive a personal invitation from Peter Doherty with instructions to burgle his house, graffiti his walls and scandalise his personal bidet.
Twitter, at its best, is a great way to massage your ego (ooh, 15 more followers!), or given my day job, chat with readers (they loved X feature on the site, they thought Y was dull, or words to that effect) and, as I wrote last week, to get breaking news out quickly. At its worst, as Conservative MP Louise Mensch highlighted this week, it's a hot-bed of misogynistic idiots using it to abuse, scare and lambast women in the public eye in the crudest manner possible.
