Blogged.com is a blog directory and a tool for discovering new blogs. Unlike other directories like Technorati Blogged is human edited. Users can rate the blogs, comment and submit their favorite blogs.
Each blog is ranked in relevant categories with a score, this score is assigned editorially by Blogged.com. Users can also rate blogs, you need to login to rate and review. Blogs are arranged from best to worst in each category. Each blog will have its own page, with a thumbnail image, blog URL, Description, Tags, Review score, recent posts etc.
Blogged is designed well, simple to use and you will find lots of good blogs on each category front page. Now a days Technorati is not very relevant, its all confusion. Blogged is going to fill this gap, i am sure if you give a try you will find a lot of good blogs in your niche.
