Pinboard is a (newly) supported Channel for IFTTT, so a recipe for Pinboard -> Wordpress is simple to create. https://ifttt.com/pinboard
You can do a lot of hacky stuff with IFTTT if you play with RSS too. For reference, I made a Reddit image auto-downloader in IFTTT by using RSS and Yahoo Pipes awhile ago: http://minimaxir.com/2013/01/if-cute-then-happiness/
IFTTT is pretty awesome but I've been using the Postalicious plugin for a while to create a linkblog out of my Pinboard bookmarkings via RSS. Speaking of, RSS + IFTTT is great as well. I'm hoping the Google Reader demise indirectly cultivates additional innovation with RSS for these kinds of things.
Just proof of concept. Honestly, if an automation service existed that had the simplicity of IFTTT (in terms of triggers) and the flexibility of running your own code to transform the inputs/outputs, that would be my dream startup.
