I don't know if the 'official' attendee number for this year's conference is 12K, 14K, or 16K... but I do know that it feels like more people are here this year than in the past couple. You've got to believe that's a good sign for Java. :-)
I attended the JavaOne Alumni "Fireside Chat" last night. Even though I've been an alumni for many years, this was the first time I've been able to make this and found it very interesting.
It's the day before JavaOne! Hopefully you're already into it on Monday...
