Came across this article about how Sunderland of the BPL is taking away people's season tickets for persistent standing. I think this topic has been argued out pretty well on this site, but I found it interesting that a team / organization was actively trying to get their fans to sit down. (HT: John Infante)

When I went to the Ohio game in 09 we stood the entire game with the exception of halftime. Don't know how much I has changed since then, though.
2013 will be the year.
