This returns your Followers on Twitter, sorted alphabetically - names starting with digits first, then capital letters, then small. It accommodates up to 100,000 Followers, so there's room for growth. In case you're wondering, I ask for Follower Count to get it as a number to input in mathematical calculations to loop through the right number of page requests to retrieve all your followers. It's not hard to get Follower Count from your TwitterID, but only as text. Yahoo Pipes doesn't currently support a way to convert text to number, which I expect will be fixed eventually.
