Lists aren't one of Twitter's more popular features, but if you're the type of person who follows a lot of people and you're having trouble keeping organized, Lists are a must. Until today, you were only allowed to make just 20 of these category lists, with a 500 person limit on the Twitter accounts you could add to those lists. Now, with a major upgrade, Twitter has upped that amount to 1,000 lists that can holdup to 5,000 accounts each.
If you'd like to make your own List, just head to your Twitter page, click Lists on the left side menu, then select "Create List" on the right, just under your profile cover image.
Now, if you ever reach that maximum amount: you need to get out of the house more often.
