If anybody that runs the website is here, may I suggest the ability to filter/sort the talks by language? Several of the talks are given in a language I'm not fluent in, and not all contain translations.
The video player makes my iPhone near scalding hot. It also lost charge while on a charger. How?
The first talks had some audio issues, hope they got it fixed
What happened with the newag talk?
