[opensuse-marketing] conference to go to

Hi all, In december, FOSS.in will happen. In Januari there is LinuxCon Australia. I can most likely go to only one of these two events. So tell me, what do you think, where would you go, a visit to what conference would have the most impact and help openSUSE the most? This ain't only about me giving a talk or not - it is also about what local openSUSE ambassadors are there, what they organize etcetera. So do you have any plans for either of these conferences? Or is there another conference in December or Januari that you think I should be going to? Cheers, Jos
