I don't really have a clue what it is except that it is favoured by the younger generation – and I'm not knocking it. But if I was to say anything to Neil Lennon about Twitter, my advice would simply be that he does not need to answer to any of these people.
He has proved himself to be a good manager, he has improved the team and he himself has also grown into the role of Celtic manager this year.
There is always a danger that you can get caught up in criticism when you are the Celtic manager. Even when you are a winning Celtic manager, there will always be someone who wants to point the finger and complain about something.
And if you lose a game when you are in charge of the team, well, you know there is an avalanche of criticism coming. That is just the way it works.
I recall getting to a stage when I was manager of the club that I was scrutinising newspaper articles and I was in danger of getting to a stage where I was looking for criticism and negativity. Eventually you come to the decision that I had to step back a little because you would go mad if you let it get to you.
I didn't quite stop reading newspapers but I did try to stay focused and keep faith with my own decisions. But the danger with Twitter, if I am correct, is that you just don't know who you are speaking to. And if you get sucked into answering complaints then you could spent half your time as a manager explaining yourself to people.
Lennon has done enough in his time as Celtic boss to be above that. He has proved he has what it takes. He has no need to feel that he has to answer to anyone giving him grief on Twitter.
