Kim O'Donnell has gathered a go-to list of people to follow on Twitter from the sustainable food world. Many are my Tweeps. She writes:
For those in the social media know, Twitter has unveiled a beta version of its “Lists” functionality, which allows you to categorize Twitter accounts however you wish. The list is an interesting way of distilling feeds by theme or topic, making it easier to keep tabs on news, particularly if it’s breaking or timely.
...I’ve just scratched the surface, but already I’ve got 25 (or maybe 27) folks and groups worth considering a follow or at least a quick Twit-peek. Check it out, and feel free to weigh in and share some of your favorites.
