We currently have a Group Blog at www.careerhubblog.com.
I am considering redesigning the blog so that it works like [url removed, login to view], where the post author has a photo and Bio attached to each post and where readers can search posts by author etc. Another example is at [url removed, login to view]
Note: I'm not looking for a full news site, or even a compolete blog redesign. The key to the redesign is to make the post authors much more visible when they post.
The blog is currently in Typepad - if we have to move to accomplish this, we would only consider Wordpress.
