One of the best features of the Web 2.0 tools is the ease with which one can extend them. Using a blog or Facebook, but want folks to hear one another’s voices? Bring in a Skype chat. Using Facebook and want to deliver a real-time presentation? Broadcast yourself with UStream. Free, easy-to-use tools are emerging and evolving all the time to help you create your own mashups. If you can think it up, there’s probably technology somewhere you can adapt to your own needs. Experiment, try to stay abreast of industry news, and be willing to learn along with your learners.
