At the moment City are a well run football club, or a successful club. By and large the fans are happy, but not at Arsenal or Man Utd. There the fans are unhappy and it's evident that there are issues with the owners. These Youtube channels provide a very effective way for fans to communicate and spread ideas. The ideas themselves can be good or bad and that depends on the contributors. On Bluemoon, after a defeat all kinds of opinions are raised.
The one area where I think there is a difference between fan channels and football message boards is that the incentive to be controversial and emotional is much much greater with fan channels. Reasoned low-key argument can be boring for the neutral but if the presenter is screaming and emotional it becomes watchable (until you get bored with it) so there is an incentive for fan channels to promote dissent to attract views.
I enjoy watching them, particularly the vlog diaries of match days, but I watch them more when a rival club loses.
Football is tribal, and part of the enjoyment is seeing your rival club struggle.
I can honestly say though that my impression of Arsenal fans has gone upwards a lot because of their fan channel. I had thought that Arsenal were a Southern club who had lost touch with their roots and were followed by yuppies but it's completely the opposite. These fans are very down to earth, and well-spoken. There are good and bad.
It's essentially fan opinion which has the potential to be distorted by commercial considerations. It's far more likely to be on the button though than views and opinions from Fleet St journalists. Indeed it makes their writing completely redundant. Why would you read what some none-fan thinks of your club, I'd far rather listen to rival fans.
I can understand that if they support OGS and a lot of fans are saying OGS out, then that might make them angry but you should be able to pick the mic up and respond. You don't have to hit someone. There probably is an argument that opinion can be distorted by the need to make an impact but at heart the arguments are genuine, and authentic. If they weren't, you would be able to tell straight away.
We don't have these issues at Man City but it's worth noting what is happening at other football clubs and seeing what the issues are.
