Being Pope may mean good things in the afterlife but here on Earth, it doesn't count for a lot on the Internet. On the day Cardinal Jorge Mario Bergoglio was elected Pope Francis, over 600 domain names were registered by cybersquatters. They must be evangelicals.
Even mistaken names like Francis I were taken.
So Popefrancis.org is not available to the Roman Pontiff, along with most of the country-specific domains, like popefrancis.fr. Even popefrancisi.com was scooped by someone.
Oddly, at the time of this writing, his Argentina country-specific domain was still available - so if you want to grab Popefrancis.ar.com, you still can. Look for domain company GoDaddy to have scantily-clad nuns stripping in the enclave advertising that one real soon.
