New problem: My notes do not have a "u-syndication" link to the app.net version like they do for the Twitter versions, because my code has no idea that app.net syndicated my post automatically using PourOver.
Possible solution: app.net could send me a webmention when they pull in one of my posts. Since I'd parse it and see their u-url link back to my post, I can at that point update my post to have the u-syndication link.
