I totally get the appeal of using static-site generators, I just don't understand why anyone would want to use it for a blog. As a programmer I use tools that are very complex; however, for those tools, there is no simpler alternative. When it comes to things that are outside of my work, I try to keep things as simple as possible, because the simpler it is the less I have to worry about it and the less sleep I loose at night over it.
You wont need post scheduling because nobody will bother to read your blog if you keep up that attitude! Problem solved
