Hello All, So a Friend(someone I am following) can only be Direct Messaged when they are also following me, ie the relationship is bidirectional.
These two lists can be aquired using statuses/friends and statuses/ followers. However is there a way (without using an O(n2) loop) to find the intersection of these two sets, ie people that can be direct messaged? (This information must be available in a remote location, so this processing is required up front) Thanks M
