Well, my conclusions so far is, if you want to make a stab at Kindle, or any publishing avenue for that matter, it has to be more than just a stab.

- Write about what you know, if that is a hot niche, the better, if not, you will make less
- Just putting it on Kindle and doing nothing else is not going to get you far
- A supporting website, blog, twitter, facebook and what else marketing technique gives you higher sales and maybe even a following if you write a series of books
- Easiest way to get reviews to boost sales confidence is to actually buy a few reviews from Fiverr, a book is not considered a "product" and therefor does not fall under the FTC's rules of disclosing that you paid for the reviews
- Including a free book at the end of your sold book with a link to an optin page to build your list is an excellent idea
- Title, description, tags, cover and reviews are extremely immportant
- Forget Public Domain and PLR, unless you spend a lot of time re-writing and adding to it.
- Non-fiction is the way to go
- Sending review copies to bloggers helps a lot
- Your earnings will grow slowly over time if you keep promoting and adding to it, less effort into marketing is needed as you grow since you now can promote to your own list

And then, there's more to it than that....
