Twitter has its positives - a brilliant communication and news tool - and its negatives - awful trolls, feeling like you're wasting your life reading about nothing - but one of the most interesting aspects of it is how we've been able to see a hidden side of certain individuals.
Who could have predicted James Blunt would be a comedy genius? Or that Joey Barton would quote Nietzsche?
And another great example is that of Gary Lineker. Of course we knew he was a great sportsman, and a broadcaster who had grown from a nervy start to being a calming presence on that Match of the Day sofa - a safe pair of hands, who would rarely say anything controversial.
But, when he joined Twitter, we certainly weren't expecting him to be so forthright and, well, just right with his views on a number of other issues, particularly away from sporting chat and regarding more serious matters.
He’s known for his recent plea for humanity in the face of the ongoing refugee crisis which, with depressing inevitability, led to a storm of abuse via Twitter, and a front-page slagging from that bastion of moral virtue, the Daily Star.
We fail to see how anyone could take offence from this tweet, which sparked the 'row':
And, quite rightly, he defended himself against those who attacked him.
And now the Daily Mail are on his case for supposedly not paying his taxes – they dedicated a whole two pages to calling him out. Such a great use of time, clearly. Anyway, Gary isn’t having it:
So what about the other times when Gary has been resolutely unashamed to stick his neck out for what he believes in? Well, step this way...
