So, you want to publish a site and want to do it now? As in, really right now? And for free? And you are a Nikola user.
If you are a Dropbox user, open an account at Pancake.io Then set your OUTPUT_DIR to something like /home/yourname/Dropbox/Apps/Pancake.io and build. That's it. No deploy step.
Or open an account at Backlift and set OUTPUT_DIR to /home/yourname/Dropbox/Backlift/foo where foo is your site's name as configured in Backlift. Build. No deploy step.
Each of these services has advantages and disadvantages, from lame URLs to costing money, but hey, for a quick thing they are cool. You can always upgrade to the real thing later.
