In theory, you could build a site that functions entirely with just HTML and client-side Javascript. I've done it before and, so long as you can expose a directory listing on wherever you keep your 'blog posts', you can just consume it with JS, perhaps transform Markdown into HTML (or just save as HTML). You won't get an editing/admin section though, naturally, as you won't be able to save a file to the server from client-side JS. Something like this or Node bridges that gap. Have you seen http://www.spintoapp.com/ http://www.spintoapp.com/? It just launched here the other day, and might be exactly what you're looking for. (Jekyll as a Service, basically)
