Why do I see scrollbars on the example chokeboards for videos that take up the entire container? area1 class has overflow-y:scroll. Maybe this should be removed from there and moved to text-block or video-block depending on what makes sense. Unless you do want the gutter between containers. But there are better ways to put gutters between containers.
Hey! I'm the creator of Chokoboard, I've never expected to see it on the first page of HN. Thanks for pointing that out I'll change that
Still see the scrollbars a week later. Would be interested to know what kind of bump you saw in traffic being on front page of HN? When my product was on front page of HN for a day or so I saw maybe 2000 hits on the site.
