The press is full of the fact that Facebook is going to crack down on fake news. One of the methods is going to be the amount of time people spend reading what is linked.
Great, so you post something which is of interest to 56% of the UK but the other 44% who will never believe it get there first. Facebook has shut down the account before the people who want to read it get there...
Nice. Ah well there's always twitter.
What I find interesting is that there is not a single word of caution to be found on Google News over this.
