Kinda missing the point.
One of the greatest of LittleBigPlanet's strengths is the ease with which you can share content. It's not just about creating content, but rather having a large audience and feedback available for any content you create, as well as an incredibly robust selection of content for those who'd rather play than create themselves. It's YouTube-esque streaming and rating system is what has given the game the life and longevity it has.
From what I've seen, this game only allows you to create levels and games for yourself. It doesn't allow you to share content, and even if it did, you would be unable to share content across platforms. This is one of the reasons Media Molecule planned for LittleBigPlanet to be exclusive to one platform from the getgo.
