Nested selections/joins/bindings/whatever have definitely been the biggest stumbling block. A tutorial would be much appreciated.

Results after the first one fail to load in the latest Firefox. It looks like a Firefox bug btw, the style and script tags are not being added to the created iframes (except the first, which is always ok) unless I mess with the timing, either by using a 100ms delay in setTimeout() or a breakpoint with Firebug.

PS: it's a fantastic tutorial, thanks for writing it!

These tutorials have been excellent so far. Do you have an RSS feed that publishes when new tutorials are ready?

hazzen, cool that you are going to cover them. What kind of project are you working on, if I may ask.
