Looks like the techies attending NECC will be using the event to give educators a taste of blogs, podcasting, etc. It is a great way for those offering content and those willing to serve as an audience to experiment a little.
One podcasting venture will come from a small group of ADEs (Apple Distinguished Educators) – try ADE Postcast for a preview.
If you are unfamiliar with the iTunes podcast option, you should take the time to learn how iTunes now makes major podcasts available to any interested listener (Washington Post article).
