Lists are extremely useful. You can group people together in Twitter lists so that you can go and just see those people’s Tweets. It’s also useful because you don’t have to follow the people you put into Lists and so you don’t have to follow them but still get to see their Tweets. It’s another way of seeing people’s Tweets if and when you want to and you don’t have to be following them. You can have 1000 different lists and put 5000 people in any of them, one or more.
You can create your own lists or subscribe to lists created by others.
To create your own list, go to the gear icon drop down menu in the top right navigation bar or from profile page just click on Lists. That’s where you go to look at Tweets by people you’ve put in Lists and manage your lists etc.
To add Tweeters to your lists, click the gear icon by the the Users profile and you’ll see ‘Add to List’.
Whether to keep your Lists public or private is up to you. If you have a bunch of confidential clients, influencers and competitors you want to ‘watch’ what they’re Tweeting about then you’ll probably want to make those private. If you’re making a good list of contacts in one field or location that others might want to follow we’d suggest you make them Public, and that you name them clearly and positively and you’ll get other people following your lists.
To follow other people’s lists, from their Profile click on Lists and subscribe.
