I think I now know why Reddit was so generous with all of the Gold. The app, although very fast and responsive on iOS, lacks many of the features that Alien Blue had. I could find zero integrations with any third party services. The cool thing about Alien Blue is, if I was a stoplight and didn't have time to read a linked article, I'd just add it to Pinboard and get back to it later.
Another major failing - there isn't an option to always open links in your browser of choice. At least use a Safari View Controller, for pete's sake.
EDIT: It looks like I can choose to share a link with the ... menu option. I can then share to my Pinner "Quick Save" option to save to Pinboard. Not sure how I missed it.
