Totally agree on the social media. I will admit to not using it myself (I've got no friends, my dinners are a bit boring and I don't have a cute cat).
Having said that jokingly social media can be a great tool. RU effectively makes it's games an "event". They can virtually sell out Twickenham for the Army vs Navy game.
So lets make our games an event, a place to go for a good afternoon out. How? So leading up to a game post how you can't wait to be there, post pics of you and your mates enjoying a drink in the club, post how good the game is etc etc. If 3 people out of your perhaps 300 Facebook friends come to a game and other posters friends do the same how good would that be?
