Olivia Mitchell is the person behind the Speaking about Presenting blog. She is one of the true leaders in the global presentation design community and collected and synthesized input from 40 presentation experts, bloggers, and other enthusiasts into one blog post: PowerPoint design in 2009: does design matter?.
Well done Olivia. 
And well done presentation design community. Over the past few months a group of people around the globe really started to work together, comment on each others perspectives, exchange ideas. There are not that many blog subject areas in which this happens. Great. Join in if you want. See my improvised blog roll (I forgot many names there, or go to Alltop Speaking to get a flavor of who is out there).
