What did the Republicans learn from Obama's "long form" Birth certificate that they didn't already know?

I mean what was so F'ing important that they all had to squawk their heads off incessantly? What was SO important that they JUST HAD to see the "long form" BC? Also, what were the "shocking" things that Republican hero Donald Trump was learning about Obama's birth? He hasn't announced them yet, so I'm wondering if anybody knows?
