No shower cam. No diary room. No Julie Chen. Those are just a few of the problems with the newly launched OurPrisoner.com. Billed as the first-ever 24-hour interactive Internet reality show (but really a not-so-subtle ad for BigString.com, an e-mail security service), the site allows viewers to monitor and dictate the every move of 35-year-old Kieran Vogel, who’s confined for six months to a New Jersey home. Vogel’s supposedly a kook — we’re treated to his thrice-weekly therapy visits! — but sadly, unlike Big Brother all-star Jase Wirey, he has yet to show any propensity for flapping his arms and clucking like a chicken.
