I saw the trailer and read the Guardian review of the film, but until the review hadn't noticed Sorkin wrote the script, and similarly hadn't noticed it was a real name using story about the facebook origins. Also, I must confess I had no idea who Zuckerberg was until said review (& the trailer). (Not having a facebook myself.)

Having read the article you just linked, I guess the writer might miss the reason why Sorkin thought Zuckerberg would like the Lemon-Lymon episode; the online community actually beats Josh into retreat there, after all, and he fails at the internet.
