After capturing a list of the people you follow, this workflow enables you to:
- assign twitter accounts to different groups (e.g. via RegEx over the profile)
- use the group boolean columns as the basis to create and populate lists*
- mass un-follow people so that your core twitter feed is streamlined
* I noticed significant instability in the Twitter list APIs. A workaround (that was still a bit flaky!) is to split the accounts into groups of 100 and use Tweetdeck to bulk add people to lists. The
spit() function in the gist is how I tackled this.
