Add all the Twitter users you are following to a Twitter list.
View addTwitterFollowingToList.js
/*
Author: Irene Alvarado
Description: Add all the Twitter users you are following to a Twitter list.
Useful if using services such as TweetDeck to search only through people you are following
To run: first install twit through node `npm install twit`, then run `node addTwitterFollowingToList.js`
Change your API keys and list configurations where the comments say TODO.
Note about API limits: Twitter sets limits for how many users you can add to a list within 12 hours.
You can’t perform that action at this time.
