Incredible as it may seem, I didn't get to see ONE SINGLE TALK in the last two days of the conference!!
Why!?
Because:
1) I had to prepare my slides for three different talks;
2) I had to speak to a lot of different people regarding several different projects in which I'm involved;
Bottom line: while I really enjoyed the last days of the conference, I spent them doing all the things you do at a conference apart from attending talks (and believe me, I did it a lot). I met tons of people. I learned lots of stuff. It's just that... I didn't get to see talks... :-\
As for the things that have been put in motion during this YAPC... I'll be letting you know about all them pretty soon :-)
