Yeah, tickets to BlizzCon and places like video game fairs would be a good idea. I would suggest real prizes for game contests as well, sort of like what you did back in February, but you'll need to drive more activity up and have more people who are dedicated in playing the games.
And I'd like to see more than just a separate area and a shiny title for Premium members.

You know, give people motivation to actually want go Premium for the right reasons.
