OpenShift.io is "Currently waitlisting registrants." and I think it will only give .io subdomains, not .com subdomains.
I like being able to give my personal website as http://peterburk.github.com because the .com subdomain makes it sound more professional somehow. Non-English speakers will recognise a .com when they might not recognise .io as a URL.
