A must when blogging is of course to post a tweet whenever you publish a new post! It took me literally 15 minutes to set this up with Huginn.
There's a RSS agent that checks a feed with an interval of your choosing and Ghost of course has the feed built in at
/rss. All I needed to do was to auth with Huginn's Twitter service and add a nice little formatter to include the post's tags as hashtags.
If you want to import the entire scenario I made a gist!
