Mitch, I also love SNAP! If you didn't see it, they added Medium support in their last update after Medium released their write API. Medium also has their own WordPress plugin which will allow you to broadcast there easily and quickly too.

if you're game, there's a few other tools you might think about adding to your workflow:
First you should know about http://indieweb.org and take a look at their WordPress section at indieweb.org/WordPress. It'll help you more easily suck back likes and replies of your syndicated posts to Facebook, Twitter, Google+, et al. so that you own all the data and comments from them. (This will also make your blog look more "lived in". They've got a cool range of other nifty tools for making/using your WordPress blog -- all of them free.

One particular one that integrates well with SNAP is Syndication Links [https://wordpress.org/plugins/syndication-links/] which pulls in the URLS of the social sites you send your content to with SNAP and displays them under your content so you (and others) have a better idea of where you've sent them in the past.
