This Fuel framework looks like they took Kohana 2.3.4, cleaned up some bugs, added the command line utility and migrations to it, and that's it. Awesome!
Really only one thing that seems to be missing (and maybe it's in there but not in the documentation): how do you put validation in the model, so you're not duplicating model validation in every action that processes submitted form data?
Other than that, I would also agree with what others have said about the tone of the developers -- it's not going to help the growth of the project's community in the long run.
