Sam Rose on social networks
Also, recommendation: get on twitter and identi.ca too
Lots of people are interested in OSE there, as I have been talking about you in those spaces.
sorry, one more suggestion: use ping.fm to update twitter, identica, facebook, etc which can be done right from your chat client.
step #1: make an identity on these networks and sites.
* twitter * identi.ca * youtube (you probably already have this) * archive.org (optional, but a good place to archive audio and video content) * bliptv * del.icio.us * facebook * http://socialmediaclassroom.com/community (good to get yourself in front of educators who will be sympathetic to your work) * any ning network you think is useful
Once you have that done (it won't take you too long), I will help you come up with a strategy for using them, and following them, that is relatively quick and easy.
