A month ago, Twitter said they would be rolling out Twitter lists. That day has finally come and almost all users can create their own lists. Lists are basically a way for Twitter users to create groups of Twitter users into categories. For example, you can find the Search Engine Land team all in one Twitter stream at twitter.com/sengineland/team.
How does one create a Twitter List? The first thing you need to know is that the owner of the Twitter account can make a Twitter list in the format of twitter.com/username/listname. Only the Twitter username can define who goes into the list under their own account.
You login into Twitter and at the top, you should see this:
Click on create new list and you will see:
To add people to a list, find a profile and click on the “Lists” drop down. Then select the list you want to add that Twitter user to.
As you add people, they can then find what lists they are on by clicking on the “listed” link on their profile section. The listed link goes to http://twitter.com/USERNAME/lists/memberships. For example, you can see the lists I am on at http://twitter.com/rustybrick/lists/memberships.
There are many desktop and web based applications and software that created these types of lists for you. Now, Twitter allows you to do it directly on Twitter.com.
