Twitter lists are timelines you build yourself, consisting of friends, co-workers, sports teams, you name it. You’ll immediately notice if you’re one of the small group as the announcement will display right at the top.

The way lists work is very easy. When you search for someone or visit someone’s Twitter page there a list button to add this person to your list.
Whoever you follow in a list does not appear in your general timeline, unless you follow them there too. This is a great feature as it allows you to create lists for specific topic or events that you can follow without cluttering your main Twitter stream.
Lists can be either public or private. A public list allows you to share – you can send them the link, I have not seen a search for lists – a Twitter stream with others. Great for sharing a bunch of Twitter resources at once, I see lots of opportunities for it. A private list can only be seen by you. This would allow you to follow something without others seeing you doing so.
I started right away to create a Greenpeace Twitter list. As you can only see it when you are part of the beta testing group, I’ve posted some screenshots below. The first one is how you view a list on your own Twitter page. Also note the lists feature just below the search on the right. The second shot is the actual list pages as you see it when you visit it.


From what I have seen, I like the lists feature. And you?
