Amazon has a little heard of feature called Kindle Publishing for Blogs. You can check out the site here. When you first click on the site it says that you can only view it using certain internet browsers. It's a lie. I have used several "non-supported" browsers to access it and it works perfectly.
Here's how it works in a nutshell:
You upload your blog's RSS feed to Amazon. People can then subscribe to your blog through Amazon by paying a monthly fee decided by Amazon (usually between $.99-2.99). The idea is that they could read your blog on their Kindle device rather than on the computer. You get a percentage of the monthly fee paid.
The reality? This idea sounds nice on paper. But why pay money for something you can read for free? 3 of my 5 blogs are "published" on Amazon and I've only ever had one subscriber that lasted for a few months. With most Kindle devices having internet connections and most blogs offering an email option, there's really no reason to be paying money for a blog subscription.
I keep my three blogs up on Amazon just for the heck of it. I figure it can't hurt and if nothing else it could maybe redirect a potential new reader to my actual blog site.
