Just to repeat a few things.
she mentions "rivers of online abuse" aimed at Laura Kuenssberg. My concerns are the show she did about the referendum that implied Corbyn was to blame for Labour performance. The section on the phase when Labour was asked to take over ignored the actual presentations from Brown and Lord Darling. It was just wrong. Also recent interview reveals that Labour policy on EU trade is very different to Conservatives, this is just not what comes over.
Main thing though is the remarks about online. --"propaganda sheets like the Canary"...reporters worry about truth in a hyper partisan world...
As far as I know the BBC reported two heckles during 2016, both against Jeremy Corbyn. On Twitter and other sources it has been suggested that one was connected with Portland Comms and the other with the Lib Dems. Thing is I have never found any contrary reporting so what to think?
"Facebook messages tend to be shared among the likeminded"
Newspapers have a bit of a funding crisis and spend less on news resources. opinion is the thing. so they become tighter on marketing and discipline. online has more variety as far as I can tell.
You are offering an apology for the rest of Fleet Street and the Guardian Corbyn knocking. My guess is that quite a lot of readers will move online to find media they can trust or talk to each other.
Guardian Media Group so hostile to online in print version it is hard to accept the online version as genuinely part of that scene.
