I've decided to [...] just upload them all so that you can download them all in preparation for this year's ZendCon. As you listen to these paragons of PHP goodness think of how wonderful it would be for you to be there in person and talk to these founts of wisdom. You will find several of the speakers from last year at ZendCon as well as a bunch of new ones. While you may have missed the early registration there is still time for you to get your tickets to ZendCon 2011.
There's about 75 of them for you to enjoy and not much time for you to catch up - this year's ZendCon happens in October (17th-21st) in Santa Clara, CA. They have a great list of sessions for this year's event too (which I'm sure will all be recorded for release next year as well)!
