as a slight aside - I note that Kate was charged in relation to the Communications Act 2003 which superseded the Telecommunications Act 1984. Facebook was founded in 2004, YouTube in 2005, Twitter in 2006. People are being prosecuted using outdated legislation that does not reflect the realties of social media in the 21st century.
I think this is central and we are going to see problems with this Act over and over again until it is amended.
In the olden days before the internet if you said something down the pub that was speech and if you put it in writing to an individual that was a written communication and if you distributed a written communication more broadly that was publishing.
The law has not kept up with our new habit of just chatting but doing it in writing on the internet. I would hate for there to be written evidence of every bullshit pronouncement I have made down the pub since the mid 80's yet more and more this is how we are socialising, this is how we are engaging with each other - on social media platforms, in writing.
