# those stupid pigfuckers at twitter don't include your followers or
# following lists in your twitter data export by username, only by numeric
# userid, so you can't easily take your social graph with you, if you e.g.
# want to use nitter to RSS follow certain twitter feeds.

# additionally, the export includes your twitter user lists: but only the
# names and IDs of the lists - *none of the actual userids or usernames that
# comprise the lists*.  just that you have a list of id x and name y, not
# who's actually on it.

# twitter are fucking assholes.
# i deleted my account right after this export.
