For my research I got 10 user ids and found their following friends and followers from the Twitter profile using http://twitter.com/account/redirect_by_id?id=.
I downloaded the same info from an API I wrote.
As shown in a chart here, http://facstaff.elon.edu/byunglee/twitter/twitter.jpg
the two results were the same except seven areas: the count of 6 following (yellow marked in the picture attached) and 1 follower (cyan marked) came out 0 when I got them through API, even though there were non-zero numbers for them on the Twitter profile pages. That’s what happened yesterday.
When I tried to do it again, today, I got the same friend IDs, 17874544 57963332 17093617 23060343 813286 20713061 287413569 58379000 50055701, regardless of the id I entered for $api_call = “http://api.twitter.com/1/friends/ids.xml?user_id='364531155&cursor=$string_int”;
