Minor update to the blog. I am now making use of Ghost's "Featured Post" feature.
The front page now looks for the most recent post flagged as "featured" in a stack of the most recent seven posts, and displays an excerpt of it on the home page. If no flagged posts are found in those 7, then the most recent post is displayed instead.
I added the search for featured post function to my $ghost object for PHP, and adjusted the home page to use the new function. Screwing around with APIs is fun.
