Why does Digium|Asterisk World Exist?

Do not miss the presentations, (any if you can manage it,) but I am looking forward listen to one particular speech tomorrow.
Digium Founder and CTO Mark Spencer will deliver the Digium|Asterisk World keynote address on tomorrow, March 18 at 12:30 p.m. The presentation, "Why does Digium|Asterisk World Exist?" will focus on the role Asterisk plays in successful businesses.
After that, day after tomorrow, Digium CEO Danny Windham will deliver a keynote address at VON, "An Open Source VoIP Primer," on Wednesday, March 19 at 9:30 a.m. that will examine open source trends and business models.
Happy VONing!
