This was my lecture given at the WordCamp Dallas 2008 event held at City Hall in Frisco, TX. A fully documented and hyperlinked version of this video is also available, entitled 45 Ways to Power Up Your Blog.
Many people seem to find it more useful since the references can be more fully explored, however some people have told me that the lecture helps to bring things together for them.
P.S. – Watch for the cameo appearance from Frisco City Mayor Mike Simpson!
