Barcamp Vsetín 2012 (in Czech). We are still waiting for the last third but do not hesitate to watch 20 already published video recordings now. The official program is here. These video recordings are also on Vimeo, so you can directly compare which service is better.
Thanks for watching!
PS: Do you know or planning to visit another conference like Barcamp? Do not hesitate and tell us its name! We can process it as well.
