OK, a couple of weeks ago I shared Clue #1:

"We’ve just about firmed up our first guest speaker for the 2007 Innovate Conference at Granger. (He owns a Mac.)"

Well, now, we’ve officially firmed it up. Only problem is no one has guessed the speaker based on the first clue. So, here’s Clue #2:

He has some experience as an evangelist.

The first person to correctly guess the guest speaker will get a free registration to Innovate 07.
