Amazon and Kindle are offering, through a BETA program, for people to be able to get various blog subscriptions delivered wirelessly via Amazon Whispernetand updated throughout the day to their Kindles for a monthly subscription fee.
Kindle blogs are fully downloaded onto your Kindle so you can read them even when you're not wirelessly connected. And unlike RSS readers which often only provide headlines, blogs on Kindle give you full text content and images, and are updated wirelessly throughout the day.
With this being said, if you reading by blog through an email subscription, RSS feed update (like Bloglines or Google Reader), you just bookmark it, whatever, you can still do all of that and it will be and always will be FREE.
However, if you would like the blog posts delivered to your Kindle, in a format designed for Kindle, and available on the following devices; Kindle (Latest Generation),Kindle DX,Kindle (2nd Generation),Kindle (1st Generation)you can now get a monthly subscription to this blog. It's risk free—all Kindle Blog subscriptions start with a 14-day free trial. You can cancel at any time during the free trial period. If you enjoy your subscription, do nothing and it will automatically continue at the regular monthly price of only $0.99.
Here is the link to the Subscription Service for my site, for those interested. Just another use for those who love their Kindles.
Again, you can still always view it for free online, via your smart phone, Nook, etc-this is just another way of being able to view it.
