This question claims three interesting limits about primes. I think it is poorly phrased, in that there is no context, source, or effort; further, it's unclear if any of the limits are related.
That being said, I think there might be some interesting math behind it and would like to offer a bounty. I was wondering about the etiquette of such questions, basically asking: is it poor form to bounty a question that might otherwise deserve to be closed/edited?
