Talk from Google I/O 2016 about the design vocabulary: keylines, jank, bleeds, affordances and more. To collaborate successfully, you first have to be able to speak a common language.
Frank Chimero's talk on the Build 2010 Conference. I like this talk especially because Frank touches the essence of the creative person in the design process. Also interesting points about the current state of the internet designs, the future and what we as creatives can do.
Webdesign conference with a great speakers list: Andy Clarke, Tim Van Damme, Jina Bolton, Simon Collison, and many more. Web designers with great talent and inspiring people.
