What options will there be that you can share a project to?

Yes, but I'm not sure what they'll be/how they'll work yet.

I believe facebook will be an option, among others, but there'll also be embed code in there so you put your project most anywhere.

One reason I like this whole new setup is because there isn't really an upload.
When I read Lightnin's comment, I was like, “Pfff, how you can you get the embed code if you haven't even up- ohhh.”

Would twitter work? Since it has a pretty strict character limit, I don't know if all that would fit.
