Hey everyone,
I decided to have some fun with my Saturday afternoon and whipped up a pretty simple RSS reader for use in Pythonista. You can add feeds (can't remove them yet), view the latest items, and click through to view article content.
@kishner on Twitter mentioned I should post it on the forum, so here it is!
I'm sure lots of things could be improved, so if you add anything or see a bug (I'm sure there are many), please fork on GitHub and share your improvements. :)
