So what's the second biggest Mac OS/iOS developer conference?
But, we're on the opposite end of the spectrum. We intentionally keep it small, so everyone can have a chance to talk with everyone else. We just announced our date for this year (9/23-25) and more details will be coming soon: http://www.secondconf.com/ if you're interested, you should follow @secondconf on twitter.
(minor edit to fix typo and add twitter info)
WHEN: September 11-14, 2011 WHERE: Denver, CO
For Mac:
