My Cool Stuff blogroll is a dynamic mix of favorites and others which reflect topical areas of interest.

Here are some highly recommended additions:

• TEDBlog:  TED + Blog = cool
• Presentation Zen:  Fantastic know-how about being a better presenter, but much more than that, too, such as this post on Wabi-Sabi.
• english cut:  Everything you want to know about quality.  Period.
