Hi, I'm one of the creators of the landing page. We thought traditional beta signup pages were boring (ie. Launchrock style) so we added a "Ravn Hunt" game to our landing page. Our landing page was pretty traditional beforehand, but after the game, user conversion went up as people became more engaged, and kept playing for the invite code.<p>It also helps that we invite the top 10 users who achieve the highest score everyday so that people have a goal to reach to get the invite. And of course, the Facebook share button helps with spreading the word.<p>---edit---<p>Here's a pic of our old landing page <a href="http://i.imgur.com/ZhURi.png" rel="nofollow">http://i.imgur.com/ZhURi.png</a><p>It was pretty straight forward, full size image in the background with a simple Request Invitation button in the middle. Hope that helps.
My coworkers are wondering why you're encouraging potential users to shoot your mascot/namesake, but my coworkers are nitpickers. That was fun!<p>If you do: $('div.ducks').mousedown();
in the developer console it's pretty hilarious.
I had top score until someone got a score of 100001158 (mine being 3385. You may need to take extra measures to ensure the scores are valid and from the game.
