There's lots of startups who can't afford a trip to go to Vegas.
But, even if every developer could, they simply couldn't fit into a conference hall. How many VB developers are there? I kept hearing there were three million when I worked at Microsoft.
So, how do you reach the other 2,999,000 that can't get to Mix?
Video. Audio. Text.
Who'll do all that video, audio, text?
Why do the press get front row seats at almost every Microsoft conference I've ever been to? Even the PDC, which is a much more developer centric venue than Mix is?
Ahh, business value.
