Hiro mumbles the word "Bigboard." This is the name of a piece of software he wrote, a power tool for a CIC stringer. It digs into The Black Sun's operating system, rifles it for information, and then throws up a flat square map in front of his face, giving him a quick overview of who's here and whom they're talking to. It's all unauthorized data that Hiro is not supposed to have. But Hiro is not some bimbo actor coming here to network. He is a hacker. If he wants some information, he steals it right out of the guts of the system—gossip ex machina.
