Set up a service where a user can put in a blog's URL and discover how many posts the blog has, how many comments and what the most commented on/linked to posts are.
Bloggers then put a widget on their sites and when people come to my site, they'll be able to see statistics on many different blogs and bookmark those which they like based on those statistics
A widget that bloggers can use to help their visitors find the most popular posts on their blogs
if I am the first time visitor to [url removed, login to view], what post's should I read? my widget should be able to tell you this, and other stats about the blog.
I need a directory listing blogs and stats about these blogs on my site.
Other ideas appreciated!
