Thanks! I'll share what I can. I don't track site traffic (but I can tell you that I've bumped Heroku up to 4 dynos to keep response time solid) but I do track media traffic, since I pay for that separately. I've already served over twice the video bytes today as I did all day yesterday. Those are probably mostly the demo video. [1]

The main thing I track is subscriptions, and free trial conversions. Subscriptions are up an impressive amount--proportionally about the same as the media traffic, actually. It will be interesting to see if the conversion numbers change.

Credit for the site design goes to Primate in Scotland [2]. They did a beautiful job with the design as well as CSS coding, and I couldn't be happier with the result. Any remaining issues you see are my fault. :-)
