Or his tweets. I pasted them into Twitter, and they're all slightly under 140 characters.
That's possible, though I have no idea how all that works! The person writing them would need to have access to the episodes in advance in order to get them posted to OnDemand in time. Or, heck, maybe they're written by Esmail and/or his writing team, but the USA marketing team uses the formal descriptions to make the show sound more accessible? (Which is rather silly, since if you're watching Mr. Robot, you're already probably fluent in textspeak. ;)
Slightly more on-topic: I'm intrigued by how the show blends real-world names and fake ones. They'll name-drop Apple and other brand names, and they'll hang a photo of President Obama and in the pilot cited Jeh Johnson, the current Secretary of Homeland Security. But as far as I can tell, the computer screens seldom show real companies, like when Elliot was researching himself this week. And when he hacked Gideon's email, it looked identical to Gmail but had a different name I don't remember. I didn't recognize any of the services he used, though they appeared just close enough to sites like Google and Twitter to pass muster. Could it be a copyright issue, akin to how, say, L&O:SVU looks up perp profiles on "Faceplace"? (Then again, I seem to recall him visiting real-world sites like Instagram and Eharmony when hacking Krista. Maybe I'm just totally wrong on all this, but the blending of real and fake is really fascinating, especially given how the show plays with this being an ECorp-ruled alternate universe that has so many elements of our own universe.)
