Twitter recently deployed a killer new feature called “lists”. Basically, it’s their version of groups that can either be public or private (and you don’t need to be currently following someone to add them to a list). For example, Robert Scoble created a list of Tech News Brands that I really enjoy. It’s features like this that allow a more functional real-time web (and it’s one of the reasons that I’m finally using my twitter account).
