Get a second blog maintainer
We try to have two maintainers for every service: https://trac.torproject.org/projects/tor/wiki/org/operations/Infrastructure
I think only hiro knows how to log in to the blog and fix stuff? Or worse, there is no such thing as logging into the blog (i.e. there is only the web interface), and fixing things requires filing tickets with the current hosting provider? And in that case the right answer is to document how to file those tickets, who our contacts are, etc, so somebody else can do this process if needed?
Is Mike this person?
