(Unofficial) NewsBlur saved stories exporter
Exports your saved stories from https://www.newsblur.com/
If you use the source from git, you'll need to download the dependencies using Composer.
Copy newsblur.ini.example to newsblur.ini, edit that file and add your own username and password.
Then run:
php export.php
If all goes well, your saved stories will be exported to a single file named starred_stories.json
