my.SketchUp is truly a beta product for us, and you're going to see the lessons we learn there manifest in new products in other places. For example, the new model viewer in 3D Warehouse resulted from testing we did on a new display pipeline first exposed in my.SketchUp. You may have also seen yesterday's "SketchUp for Schools" announcement— also made possible by the my.SketchUp beta.
I can't speak to future unreleased products, but you should get a sense for the way we're working here. Certainly, Trimble Connect has an important role in the future. In fact, you can see another my.sketchup integration there if you log into your account at connect.trimble.com
I think you make an excellent point about self-paced tutorials, and I hope we're able to show some improvement in their support in my.SketchUp in the future. I'm not sure 3D Warehouse is ultimately the best way to access training materials like this, though of course it is a functional way to do so today.
By not requiring new users to create an account before trying my.SketchUp, we intended to lower the barrier to learning about 3D modeling in SketchUp. We currently require users to create an account and log in before they can save a model. Local storage isn't really a good solution for browser/cloud applications like my.SketchUp and Trimble Connect.
