I'm waiting for TPT to get sued for copyright infringement. From what I've seen of plans purchased by my wife and/or her school they tend to be distributed with copy protected content that have specific licenses preventing commercial redistribution. The plans will have "source" links included at the end but the distribution of the material is still happening and only after the plan has been paid for. Since TPT gets a percentage of the sale or a yearly fee I would expect the argument to be that TPT directly profits from the copyright infringement.
This seems like something that Patio11 could have (or still can) capitalize on.<p>It seems a natural progression from generating Bingo Cards, to branching out to lesson plans to facilitating the sale of user-generated lesson plans.
What stops lesson planning being done at a higher level than per-teacher? That's obviously how it is happens now making TPT a great resource but why are schools/states/federal bodies not providing the lesson plans that are needed instead of making each teacher do something unique?
