Friends Last Tweet

This returns your Friends on Twitter, sorted by date/time of last tweet, oldest first. It accommodates up to 100,000 Friends, so there's room for growth. In case you're wondering, I ask for Friend 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 friends. It's not hard to get Friend 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.
