I tend to try out websites and domains mentioned in works of fiction partly to see how much background effort the creators went to, partly because I find such efforts entertaining because they feel to me like a fiction/reality crossover manifesting in the manner of Jorge Luis Borges' short story Tlön, Uqbar, Orbis Tertius. Sometimes the site doesn't exist, sometimes the site is merely a placeholder (for example, a recurring character on the CSI television show once mentioned that she had recently set up a website, which someone associated with the show had registered and built a single-page website that redirected to the network website), and sometimes the site exists - and was created as an entry point hook for one or another variant of an alternate reality game (ARG).
What's this leading up to? Monday night I was fortunate to attend the screening of The Social Network, the film adaptation of the book The Accidental Billionaires, and in an early scene in the film Jesse Eisenberg playing Mark Zuckerberg is drinking, blogging, and building a website. I noticed that at one point his laptop screen shows that he blogs using the account "Zuckonit" at livejournal.com. Wednesday I was typing up my notes from the film screening including the post-film Q&A between scriptwriter Aaron Sorkin, actors Jesse Eisenberg and Armie Hammer, and moderated by Cathy Davidson, and I found my note about "Zuckonit". I was amused when I tested the URL to find that http://zuckonit.livejournal.com exists - but was just created today. :)
