>I think it might be the way he tries to make it sound exciting for a general audience.
Looking at other videos of Károly Zsolnai-Fehér speaking at a podium to an audience, I think he's genuinely enthusiastic about the subject instead of putting on an act. However, when combining that unusual enthusiasm with a Hungarian accent, some listeners may find it odd sounding.
Probably not, I dislike video / audio as a means to explain and update things, I'll watch the news (because the video adds to the story) but I'd rather have a text version if it's about software things.
