Scriptogr.am is a new application I stumbled across that takes advantage of your Dropbox account. It’s a web app that allows you to store Markdown files within Dropbox and have them converted into posts for a blog. It’s very straight forward and simple, which might make it the perfect solution. It allows you to customize the CSS for the page (I’ve noticed a few bugs with this) and use a custom domain. The project is still in beta, but I look forward to seeing where the project goes.
