Great Hunt!
I love apps where you also learn things and adding up to that I'm a real fan of "useless" facts (the may sound useless but in my opinion no knowledge is useless). And yeah like you wrote some well timed random and funny facts can be a great conversation starter.
Keep on the good work!
Thanks @elleok for the influence and comment. I agree, facts can be useful specially if its about learning something new. I thought it'll be funny if someone kept telling people facts and overdoes it.
