Has a user login via OAuth and lists out all the channels they're subbed to with their ids. Sidenote this is a tweaked version of an example that's on google's api docs.
I'm working on getting off of youtube and part of that effort is making a list of channels that I find enjoyable so that I can grab all their rss link thingies and only watch youtube videos from the rss feeds, slowly widdling those down until I'm not watching youtube anymore.
The code is in the url and I can't be bothered setting something up to display it in the web page though if I come back to this to clean it up a bit I may add that.
