Every so often, one of my friends will ask me a tech question, or I find a product they simply must try. Some of these friends live thousands of miles away, so I make a screencast. I have all of these available for download at www.ryanpricemedia.com as well as some text tutorials as well. I use iShowU, Soundflower and OmniDazzle to produce the videos and I rarely do editing or postproduction of any kind.
Every year I compile a list of all the Fringe videos I can find. I used to run a web site called http://bloggingfringe.com and I did some fun podcasts and other posts over there, now social media has allowed me to "lazy blog" and just collect other stuff.
