One of the problems to overcome when you are self-employed is that of setting direction and choosing which of those options take priority.

Web 2.0 is exploding and now just knowing what is being offered can take a chuck out of your day. My current goal is to update the long ignored Quixor web site with a demo of some recent projects. Now in addition to traditional text with static screen shots it is possible to add audio and video to show the application in use. YouTube, Twitter, LinkedIn, Facebook then provide the channels to push the results into the marketplace. What works best should reveal itself over time.
