It's good that you have a video showing the features, but it could use some more audio. The silent parts need a voiceover. It looks like there is enough stuff to talk about to fill up the whole time.
Thanks! Yeah, it's a pretty poorly made video. There're also too many times where I'm confused what feature I want to show next and I just waste time in the video. I didn't edit the video because that would make our webcam streams look jarring.
Definitely intend to make a better one for the outside-HN launch. Will also need decent copy at that time.
