I always get a kick out of people being against twitter. Idiots will be idiots will be idiots. Twitter is an amazing thing that is way more good than it is bad.
As for Sam, nothing good comes from that. That is a battle he will never win.
EDIT: For the record, I wasn't calling people who are against twitter idiots. I just meant idiots will find a way to be idiots no matter what. Don't blame twitter for it.
