title: get Twitter friends/followers' ids and nicknames
body: <p>I am integrating Twitter into my mobile app. I am trying to get the friends or follower's ids and nicknames. One solution that I can find out is, using "friends/ids" to get the friends/followers ids, then "user/show" to get the user info.</p>
  
  <p>However, "user/show" returns extended information of the user, if a user has a lot of friends/follower (say 1000), it will be very slow to get nick name of the user.</p>
  
  <p>I wonder if there is any API that only returns ids and nicknames of friends or followers. Or there is other lightweight approach to resolve this issue.</p>
