What about adding a feature which would allow to push posts online that would become visible only once their publishing date arrives? We could publish posts with a date in the future and sync the site. On the site, a Javascript code could handle the hiding/unhiding of posts according to their date of publication.
I can see how that can help having a blog that updates on a regular basis. I love to write articles in batches and I love to spread their publication over few weeks. With this feature, the process would be automated!
