Like JK Rowling's Pottermore, Lady Gaga's Little Monsters is all about community with some critically important e-commerce offerings.
Specifically, tickets to her "Born This Way Ball" tour are available through her site (via TicketMaster).
In addition, users can "join" the event, which subscribes them to a Pinterest-style stream of items contributed by others for that event.
TNW reports the site has gone through its beta phase and is now available to all through a simple sign up (Twitter and Facebook can be used).
Can we expect her to make available media for sale as well, a la Louis CK? We would be happy to help!
