I love the easter egg in browser console. And a very nice design, kudos to the designer for that.
The overall experience is disappointing though. Clicking on Learn More About Topic did not work. Signup has multiple issues already mentioned in other comments.
Having developed multiple community based products myself, I know how hard it is to get first users. If you can create some aspirational value for early users, that can work wonders. For example, the fact that facebook was exclusive to Harvard made it aspirational for others. Another trick is to make the entry invitation based, and let every new member invite a few others. Need for invitation creates aspiration and allowance of 10 creates social gratification for those who join. Of course, execution of these strategies is an art in itself.
