Twitter is in the early stages of unveiling a new feature called “Lists”. This feature allows users to make a list of people that others can follow with one click. It is only available to a small group of users right now but they plan to expand this soon.
There will be a few different ways to add people to a list. You can browse through the people you follow or add them by visiting their profile one at a time when the new list feature is added to the page. You can also tell what lists you are included on with the new “Lists” count feature. When you click on it you can go to a page that shows the lists that follow you and the lists you are following.
