Personally I'm still doing a livenation/ticketmaster boycott, which pretty much means a concert boycott since I don't really look around for non-livenation concerts.

Though it would be nice to see the economic squeeze hurt their monopoly, like if they can't reduce their prices to meet demand because they've overextended on credit and end up forced to sell some venues. Would be even better to see those venues then get sold out for non-livenation shows to add insult to injury.
