Why can't a lawsuit be made immediately by owners of prior art (and I'm guessing HN, Reddit both have prior art around this..)

It's called an IPR, an inter partes review [0] in the USPTO. Most potential challengers, though, are likely to save their ammunition for if and when they get sued on the patent. (And they might quietly let Facebook know they have prior art, so as to discourage FB from getting aggressive — FB might want its patent to remain officially valid, so as to be able to continue to rattle its saber at others, instead of having invalidity officially confirmed.)
