That means not looking to see if there's a 0 day exploit.
That means not even thinking about upgrades.
That means not having to be the one to figure stuff out after an upgrade goes wrong.
That means someone else worrying about if it's being overloaded. (The DDOS of love...)
That means being able to quickly send off an email (a la posterous) or similar to post. Markdown is preferable.
That means, unlike static generators, I don't have to think about re-deploying when I do anything.
I have too much to do with programming and administrations for pay -- a blog is not where I want to have to think after hours. Administration isn't fun anymore. I want to own my service, but I don't want to have to babysit it.
I don't even mind paying for the privilege, though the amount needed to justify it might be more than I'm willing to pay.
What is everyone else doing that fits the above? This seems like dumb duplicated effort.
