Matt is looking for developers to attend OSBC and add to the conference the voice of those who are actually making Open Source happen. You have a good chance to get in for free, which leaves little room for excuses.
I definitely wish I could make it: unfortunately, conference timing was awful this year. With ApacheCon Europe and JavaOne running next to each other, and OSBC just a week away from the latter, it would have been way too hard for this poor European soul to cross the ocean twice in three weeks time: as I was signed in as a speaker for the first two events, it wasn’t really like I had a choice.
Still, the program is outstanding, and I will sorely miss not being there. Matt did a great job as usual, and I’m really looking forward to attend the next edition. And to webcasts, of course!
