My 45th podcast is another presentation - this time it's an introduction to blogging. I can't say it was my best example of public speaking, but I said I'd record it and put it on the site so that's exactly what I'm doing.
Last time I included all of my presentation slides embedded in the mp3 file and I decided to do the same thing this time as well. Be careful, though - at 9.8 MB and over 28 minutes this podcast is much longer than my usual ramblings.
