Hey, I've got absolutely no problem with Joe Belfiore, the man in charge of "definition and design" for Windows Phone, apparently tweeting from an Android device. In fact, I've long raved about how much I like the way Windows Phone 8 looks, even if it lacks the functionality of Android. I've covered enough Windows Phone events to recognize that dude knows his stuff. And I dabble with Windows Phone (and soon, BlackBerry 10) on weekends, to help keep familiar with what else is out there. Using other platforms makes good sense.
But the official Twitter app? C'mon, Joe. You can do better than that. In fact, here's a a quick primer on some much better (and more functional) Android Twitter apps. Give 'em a shot.
