Up and running
So it would appear that setting up the Ghost blogging platform really is quite simple, once you figure out how to get Node.js up and running.
I opted for a VPS from Linode, running Debian GNU/Linux.
This simple test site is the only thing running on this server for now, which I suppose is a bit overkill. I do intend to move over some other sites eventually, and perhaps even get around to posting every now and then. Until that happens, this is pretty much just a playground for me to check out how Ghost evolves.
