I am trying to show a user detailed information about all the people they follow.
friends/list is exactly what we need, but has a very low limit at 20 users per request. A user needs to follow just 300 friends before this gets throttled.
so instead, you can get friends/ids and cross that with users/lookup, which increases reach to 1500 friends before failing (and then also chews up your api rate limiting for other calls)
these rate limits make it very hard to show a user results when requested and then performing an action
