I don't think this is really a worry in Australia at least. Often teachers are left coming up with lesson plans on the fly and the students suffer.
My partner is studying to become a primary school teacher and one thing that has surprised me is the level of duplication in the system. At an individual school a couple of teachers teaching the same year level are coming up with a lesson plan. There are hundreds of other schools essentially teaching to the same framework. Now I'm not advocating a completely standardised curriculum with no room for the teacher to put their own individual style in the lessons. What I am saying though is that I think everyone would benefit if there was much more sharing of knowledge throughout the system. Something like this site enables that knowledge sharing.
Yeh, my partner is also becoming a primary school teacher in Australia. I also noticed the duplication with lesson plans they were having when they went to do their practical components at schools. So I built a little app[1] to help her and her colleagues create lesson plans and share it with each other. No intention of monetising it, just wanted to learn some mongodb and rails with it.
