A couple of new blogs you may find interesting:
Jim Rait had so many good comments to add to the BBP discussion board, I encouraged him to start a blog. He apparently had already been considering it, so he finally took the leap - welcome Jim, to Design_at_the_edge.
A number of presentation professionals (and friends) have started a new weblog titled Visual Being. It's definitely worth a visit if you make your living designing presentations, and are interested in a like-minded community that is focused on professional development.
Although it's not a new blog, Tony's PowerPoint Weblog continues to be the most comprehensive collection of PPT-related news, posts and links.
I highly recommend using one of the free tools like Bloglines to manage your blog feeds. I personally didn't understand the power of blogs until I installed Bloglines and could see all of the updated blog posts in a single window. One of the first things I do when I start the day is to check Bloglines to see what's new in blogland.
