However, I'm critical of the site and the HN post.
It seems to me the post links to checkout page to increase conversion. Or at least that was the intent of it. However, this is not a small purchase and I think they lose even more by sending them to what looks a like a blind alley.
Secondly, the page has a coupon code option. Right away I know I don't want to pay the full price.
I think the product can save you enough time to warrant the price asked, but I think I would have bought it if the HN post included a 50% coupon. Especially if it they had a V1 2-day sale option. Not only I would have bought it, but I would have shared on FB and twitter. Given many HN readers are influencers that would have been a good marketing move.
All these aside, I think their videos are horrible. Especially for a $180 product. If the scripts were a bit more polished they could have covered as much in half the time. They also lack the big picture intro followed by diving into details. For example: we are able to create global styles an apply it to different objects. Let me show you how it's done....
To get very picky, the narrator's voice is a bit whiny. I have made videos in the past and we spend 1-2 hours just on polishing the script and I offered a friend with a great voice free lunch to come and narrate the video. So it can be done.
Still, kudos to the team!
