For the syndicated portfolio, you might want to take a peek at the PressForward plugin for WordPress [http://pressforward.org/]. While it is a stand-alone feed reader under the hood and could be used for creating an editorial flow, it will let you use a simple bookmarklet on your work published on another site to make a quick and complete copy of the post on your own site. Within the plugin settings you can set a "time to forward" (I use one second) such that people who visit that particular post will be automatically forwarded to the original (and canonical URL) on the commissioning outlet's site.

As an example, compare:
http://boffosocko.com/2017/06/09/%F0%9F%94%96-feed-reader-revolution-its-time-to-embrace-open-disrupt-social-media/ (which is a bookmark with some commentary pointing to my post)
to
http://boffosocko.com/2017/06/09/how-feed-readers-can-grow-market-share-and-take-over-social-media/ (which is an exact copy of my post, which only I can see on my backend, that redirects the viewer to the original on AltPlatform).

This is beneficial as you can syndicate (POSSE) the post with your own URL to Facebook, Twitter, et al. and folks who click to read will be sent to your site for a moment before being forwarded on to the original. Thus you get a ping and the original outlet also gets a ping (as well as the advertising revenue for it.) And if, for any reason, the original outlet goes out of business, gets sold, or disappears, you've got a word-for-word copy of your original and can simply un-forward it so that it can appear on your site as it was originally published. Naturally if you prefer and the outlet doesn't stipulate otherwise, you could publish the original to your site and not forward it (or even forward it for an exclusivity window of time pre-agreed with the original publisher.)

Additionally, if you're using Brid.gy for backfeed, anyone who comments on your POSSE copies will have their commentary sent to your site. While others won't necessarily be able to see the commentary (if you're forwarding the URL to the publisher's original), at least you'll be aware of it and can reply to it and get your own replies in return. I suspect that in the future brid.gy may be able to scrape commentary based on the syndicated URL so that your personal version aggregates commentary from the publisher's original as well as mentions of it on Facebook, Twitter, et al.

There are still some missing pieces I'd like to see in such a workflow for journalists, but it's slowly and surely getting somewhere.

(I've written about other parts of PressForward before at http://boffosocko.com/2016/12/31/pressforward-as-an-indieweb-wordpress-based-rss-feed-reader-pocketinstapaper-replacement/ as I also have an off-label use-case to replace read it later apps like Pocket and InstaPaper.)
