I didn't find this ridiculously hard...
I mean, it's not easy, but it's probably no harder than Jeopardy. It's about standard. I think the problem that the game is running into has to do with target audience. Most Newgrounders, I've read, are in the 13-17 age range and a lot of these questions, particularly the lit and pop culture questions, are not things that they have much reason to know yet. On the other hand, I think reviews like the one that say 'you almost have to read a dictionary before you play this' reflect a really unusual level of tardation so.....there's that too. I failed the game several times, but I beat it several times too, and I don't know that much, so it can't be all that hard.
In any case, it's definitely well put together, and it's not, as far as I know, a clone of any existing quiz games. I think it has potential as an upgraded modern version of Jeopardy, although you might have to work out some way to make the game last longer and be multiplayer in order to make it work for tv. That's all I have to say about that.
