Topsy Trending getting back to normal: Over the weekend, Topsy Trending for Twitter stopped functioning. Twitter was sending us tweets from 25 years in the future ( https://dev.twitter.com/issues/180 ), so our Trend detectors thought tweets from 2012 were just too old. We have fixed our detectors to ignore tweets from the future and Topsy Trending is getting back to normal.
