There is a section in Kindle Store called Kindle Blogs:
https://www.amazon.com/Blogs-Kindle-...node=241647011
The other thing I would check out is calibre. They have ‘formulas’ for many RSS feeds that convert them to ebook format. In theory you can create one yourself.
Finally if you use Firefox or Chrome, Amazon’s Send To Kindle extension does a good job of kindlizing blog articles and sending them to one of your devices.
