Some utterly depressing opinions on this.
Our fans who go to the majority of aways are the ones who are most affected by the ridiculous ticket prices. On top of their season tickets they are forking out over £40 for each away ticket. For that reason, these people have a better understanding of the need to reduce ticket prices rather than someone who goes to a few matches a season and are therefore more likely to participate in a protest.
The Hull game presents an opportunity to test the waters. As said above, if we as a fanbase can't do this successfully there is little hope we could get people to stay away from a massive televised game like chelsea / united away. As for boycotting home games, that is a long way off and in my opinion will only ever happen if momentum is built by the hardcore doing it at away games first.
I don't think the lads who came up with this idea are stupid enough to think that this one protest will change the minds of the premier league clubs on ticket pricing but it could be an important first step. If it works, expect there to be more planned, possibly for bigger games on a larger scale.
I'm a season ticket holder with 18 credits. I'll be buying a £10 ticket tomorrow. Not to keep the credit, but to make sure that another seat sits empty. I seriously hope everyone who is eligible does the same.
