I had hoped to get Mike Wagner, CEO of White Rabbit Group, to come to Florida and talk to my MBA class on personal branding. The logistics didn't work out so instead we're doing the workshop by Skype. Skype is a free video phone service that requires a computer, webcam, and internet access. The great thing about it is Mike will be able to show powerpoint slides and link to websites as well as see the students and have the students see him, all without ever leaving Iowa.
