It’s kind of just the nature of the beast that people are generally going to be really positive with their critiques unless specifically asked not to be. At least for people who are currently funding, anyway. We want as many new followers as we can get, so we don’t really want to step on each others’ toes and make people mad at us.
It’s kind of an unfortunate inevitability. Some people may say they want harsh criticism when they’re really overconfident in their story and can’t see there being much to critique, then when it comes in they still get defensive and take it personally.

One thing I know I’d love to see is a "Save to Kindle" extension for Word. Once I get a few more programming chops, I might well try to put one together, or perhaps create a standalone one-step publisher that abstracts away a lot of the annoying knobs-and-dials configuration that you have to go through to get decent results.

My last name is Heinz and I’m #57. I think the programmers behind this did their job exactly right. 

Is it just my devices or does the buzz page seem stuck?

Oh, and the size of the print run can be a factor too. If a book has a ton of pre-orders, that can help lower the cost per book.
