The feature on Amazon has been discontinued, so there's not much point in wasting your time in it. This post is retained for historical interest only.
But if you are looking for something similar, have a look here.
The list is not exhaustive, and doesn't even have all the Orthodox blogs I read. But it's a start, and anyone who would like to add more is welcome to do so, and to comment on them. If you add a blog, please don't forget to add the URL so that others can find it.
Update - NB
To add a blog, enter the NAME of the blog or web journal you want to add, and click on "ADD".
When it has been added, click on the "Add link" and add the URL of the blog or web journal. DON'T put the URL in the name field, because clicking on it won't take you to the blog, but only to the description of it on the Unspun site. Items on the list that are not blogs or web journals, or have no links to the URL, will be removed.
See the comments below for more information, or if you want to ask questions about this.
You can find the list of Best Orthodox Christian blogs here.
