You could try something with video. Make it so entrants have to upload it to YouTube with the WF URL in the title or something. Make the barrier of entry really low so more people can try (ie. no editing required). As for the topic... hmmm... It could be something simple like a video review of the forum and what it's about, to coming up with a list a crazy/goofy things that the video has to be about and judge on the best execution.
Or what about doing some sort of review contest - members have to review WF, maybe answer some specific questions (ie. what's your favorite post and why? to get some deep incoming links) on their own site/blog. You could name winners from the best ones.
You could have members write up guides/tutorials on set list of topics and you could choose winners from the best ones. Yay for free content!
I like the idea of getting pictures/video with the WF logo in it - especially on actual TV.
These aren't great, but maybe they spur some ACTUAL good ideas!
