The Secret Lair exists because there must be a place where ideas can be exchanged freely without being shouted down by people locked into a set of blind beliefs.
The Lair is about striking out on your own and seeing where the path takes you. It is about experimentation and exploration. Take what you need from here and use it to benefit yourself.
I may submit to Kindle Serials myself. Why? Why not? There is a lot of specualtion about Amazon's payment structure but no one has provided any real facts. The only way to know the facts is to submit a serial and get a contract.
If you submit and get rejected, what have you lost? Nothing. You will have two episodes of a series written and a plan for the rest. Publish it yourself.
The only thing I'm not sure about is whether Amazon are actually accepting the type of episodic fiction we are talking about here. They seem to be talking about 'serialized novels', which is simply a novel released in chunks. So I'm not too sure if pitching an episodic series at them would work. But..as I said, The Lair is about experimentation and I won't know until I try.
