Just heard a great online presentation by Robin Good: http://www.voxwire.com/kolabora/emerge/
He didn't hit Alado, and mentioned Elluminate as expensive. There seems to be an even lower level of free/nearly free tools, such as Y!M and Y!G that he didn't touch. Webheads rule!
It is interesting how cheap, fast, and accessible the neat technology is getting.
Webheads was just discussing what Webcams to get, and the stuff available this year is twice as cool for the same price as a year ago. Arlyn suggested we look at past message archives for what was recommended in 2002-03, but that would be no help now!
