Following count returned by API does not equal number shown in Twitter UI


OAuthed to my Twitter account (@jimwllmson)

Using GET returns a list with IDs for 1446 friends
but the Twitter Website shows @chipshipperman has 1447 following.

Why are these numbers for “Following” inconsistent?


Things like counts on Twitter are eventually consistent… they can differ depending on the server you connect to, or the API method you’re using… they’re subject to a lot of caching, as are methods like friends/ids. Also, the following count can include concepts like users without screen names (users who just follow via phone) that would not be included in friends/ids.
