Twitter's new feature, which allows for the creation of lists has now been live for about a month. Many Twitter users still don't know what Twitter lists are, how to use them or why they may be important.
What are Twitter lists?
This feature allows you to group any number of users together into a common list. If you want to connect all the funny people you follow or all your coworkers, you simply create a list. Lists can be either public or private, but the default is public. TheNextWeb.com provides a great recap of how to actually create a list.
Anyone can create one or as many lists as they want, which may turn the feature into more of a circus than an organizational tool at some point.
Why should you care?
These lists will enable users to filter the massive number of tweets coming through their stream. The user can follow the lists alone, so they focus on specific people and ignore others.
Lists also allow users to promote or tip their hat to other people on Twitter. Creating a list enhances the likelihood that your other followers will see that person if they're interested in the list title.
As you probably expected, third party applications have already been created around this new component of Twitter. The most prominent thus far is Listorious, which points you in the direction of lists that would interest you. Simply type a list name, user name or tag and you will be directed to a list of lists (haha funny right? no? okay).
Marketers have jumped on the use of lists. They are creating lists to get their companies or clients noticed. The more savvy marketers are even creating lists highlighting their brand's most avid and supportive followers to engender them into the brand even more. This is a great tactic to use while lists are still new, shiny and growing in popularity.
