I posted this here a while back and since its show hn day, thought I would give an update. We are now at 103k registered users and went to a paid model last month.

As always, would love feedback from the crowd here.

A few comments: add pictures and change the youtube link to an embedded video. For me, whenever I see a large blob of text, I skip it. I like seeing a picture to show me what it is about first.
