Today Apple has launched an official Twitter account for the App store. All I can say is it's about time! This should be a great way to keep users up to date with the latest apps, news, updates, etc. As of now, there are only a few tweets and read:

Welcome to App Store on Twitter! Follow us to discover new apps, get exclusive offers, and share with friends. #appstore

Motivation. Full-body workouts. On-demand instruction. It’s all available on Nike Training Club. Nike Training Club for iPhone, iPod touch, and iPad on the iTunes App Store #appstore

I get the feeling you won't see any free apps advertised on that Twitter.

Interesting.
