Ask HN: Looking for feedback on my new site

The url is http://www.triviatise.com I'm new to HN and was a bit surprised that I could just post my site here, especially as a noob. I just finished an alpha launch at SXSW and am looking for ideas of what to do next. So far I have used contract programmers to develop but have recently added a technical cofounder.

Should we: 1) add metagame features (this is what we are doing) 2) find more vendors to put up prizes (we are doing this too) should we go after local or national businesses? 3) fix the look and feel? 4) etc etc

p.s. if you actually take the triviatisement you get entered to win an ipad 2. I havent advertised this triviatisement so it only has 35 entries so far.
