Until recently, on timeouts we were asking users to reload the page and try again because that seemed like the easy way out. But easy isn't fun and it eats into your twitter API limit since the whole process of calculating non followers starts again.

We just pushed code that would now retry a maximum of 3 times in case there is an error while accessing your list of friends and followers from twitter. This should reduce the error messages you previously received asking you to do a page refresh.
