I know this is going to be really geeky, mainly for the link related to this video (an NPR short interview):

'Catfish' Creators Catch Digital Life In Action

"It took us a long time to figure out how to tell the story because so much of the correspondence was over e-mail," Ariel Schulman says.

It's a classic dilemma: both Pride and Prejudice and Jefferson in Paris labored to depict long, epistolary passages in compelling visual language. Their solution was to simply film people writing, and the first generation of Internet movies has pretty much done the same — think of Meg Ryan and Tom Hanks intently typing on their laptops in You've Got Mail.

But the makers of Catfish wanted to avoid those worn-out visuals — no close-ups of keyboards, eyes scanning screens, or, God forbid, outdated sounds of a dial-up connection.

"There's sort of a history of movies about life on computers, maybe starting with Wargames," Joost says. "And there's been this whole trope of close-ups of fingers and computers booting up and bars going across the screen and they always use these fake interfaces that are not the computer screens we see in our daily lives."
