Twitter Lists seeks to change how people network themselves into groups and geographies. This feature allows Twitter users to group their followers into smaller micro lists such as by organizations, affiliations and neighborhoods. This gives users the control to refine their large follower lists into smaller, focused micro communities.
Lists can be personal or public. In categorical searches like finding the best Twitterers who cover Capitol Hill, Twitter Lists are more powerful than using Twitter Search because the Lists filter Twitter feeds and searches don’t.
This new feature is getting a lot of attention, mostly because social media right now is somewhat asynchronous with the ideal of social media. That is, it is hard to meaningfully connect and engage with people with huge lists of fans, followers etc. I predict that more social media sites will enable this type of subcategorizing, so that users can gain greater control over engagement.
So, for example, different messages can be shared with friends than business colleagues. This will enable more targeted messages and relationships, getting everyone close to the true promise of social media.
