I'm probably not your target audience, so take all this with a pinch of salt ...

A. I really have no idea what you're talking about

B. Was I supposed to see a "Hacker News" button?

C. Links in submissions are not clickable, they are in comments.

D. A single, simple, very specific example goes a long, long way. I was 1:20 into your video and it was still talking about how to do things and general usefulness, with no actual example.

... and now I'm bored and clicking away.
