People keep saying 'but I've still got friends there' - then their contact details and/or advise them to leave. Maybe once you've gone they'll go to. I don't understand why people are happy funding that man, there are SO many alternatives to twitter.
This is why I deleted almost a year ago. Anyone still there is basically giving him money - no matter whether you're using the account. The biggest con is: 'I'm saving my handle so someone else doesn't use it'.
