FILM: Blog to Movie in "Bobbism"

Ben Wexler, writing of relatively funny, but ultimately canceled TV comedies like "Still Standing" and "Nikki," has written the film Bobism, where a "shy college kid learns that his blog will be the basis for a Utopian society in 1,000 years. He also finds out that aliens from the future want to kill him and prevent that utopia from happening." Although that sounds like it has potential to be hilarious, I'm even more interested in how blogs have permeated pop culture so much that it's now the basis for a movie.

Who should they cast?
