After reading the documentation, I have to say this seems to be a nice medium b/w angular and knockout. I love how the api is really small and you just use plain js objects just like in knockout.js.
This is what my partner and I are trying to do with instajams.com. We've just soft launched and are in the process of getting feedback from some friends, but the jamming portion of it is rock solid.
Found out how to do something that just blew my mind:
you can make your screenshots linkable very easily by adding a button over the part of the page, linking it to another page and then sending it to the back behind the photo.
even if the button is behind your screengrab photo, it will still link.
