Blogory is a new personalized weblog reader from the creator of Findory (an excellent personalized news service) as you click on blog posts of interest to you, the theme of the posts are recorded and the system adapts and presents future articles that you'll like.
The service is free and you don't need to sign up to use it, but is most effective if you sign up and use the personalization feature, no details or even an email address are needed.
Another useful feature is the History page, where previous posts you've viewed are stored in case you want to go back to it.
Bloggers can also add their blogs to the index here.
