Apple has opened the twitter account @AppStore and posted the following first tweet:
Welcome to App Store on Twitter! Follow us to discover new apps, get exclusive offers, and share with friends. #appstore
It'll be interesting to see what Apple does with this account, particularly with exclusive offers. The iTunes Twitter accounts are currently used to announce new releases and sales, so we will likely see something similar. There has been a second tweet from @AppStore promoting Nike Training Club.
Motivation. Full-body workouts. On-demand instruction. It’s all available on Nike Training Club. http://tw.appstore.com/4zo #appstore
