The characteristics of my ideal publishing system have been rattling around in my head since I heard the news about Posterous. I haven't really done very much housekeeping on my personal sites in a while and I wanted to reevaluate my current setup. Generally I don't want to spend a ton of time on maintenance and I want the templating language to be straightforward - i don't want to spend hours sifting through a wiki trying to figure out how to output thumbnails for the latest five entries from a particular category. If I'm not familiar with the template language, a good set of examples is a prerequisite. Nice looking templates that support responsive design and slideshows out of the box is a huge plus as is deploying through git.
Not all of the sites have to be hosted on the same system but I definitely want to keep the cost low. I'd like to stick with my current host so I don't have to migrate everything and I don't want to spend hours/days backing up and archiving data, and I've never had an issue with their service.
I'm also looking to move Ambienttraffic (this site), Lonestar Taco and Emptyhighway (which should probably be merged with Angrywayne) off of Movable Type because, frankly, I hate the user experience of writing and maintaining content. I actively dislike the tiny editing window and uploading images one at a time to the point where I just don't want to write anything at all. Although I have a ridiculous amount of experience writing MT templates, they just get to be really tedious. On the plus side, MT generates flat pages so I don't worry too much about load.
Thinking about where to put all this content
