Birdsong, the popular Twitter client for Windows Phone, is reportedly the top paid social application in 6 countries, not to mention being 2nd in Canada and 3rd in Singapore (and 3rd in the U.S. where Seesmic & moTweets edge it out).

Great news for the developers at RedBadger, we would strongly recommend you check out Birdsong if you haven't already. It's a brilliant alternative to the official app on the Marketplace and we hear version 1.3 is coming soon.
