Last week, while attending the Online Community Roundtable at Forrester Research, with encouragement on the spot from the organizer, Bill Johnston, I signed up to lead off the evening and pitch the N2Y3 Mashup Challenge. No sooner then I had put my name onto the agenda, I was approached by Jeremiah Owyang (Forrester's Evangelist for Social Media), our venue host. He asked me for a quick summary of why I was there, and what I would be sharing with the audience.
