I have been using Espresso for more than a year now, and I love it. I am considering writing a book / recording a video class / giving talks & workshops on the topic, but it is a substantial amount of work so I want to gauge interest before I start. If this material is valuable to you, please let me know by filling this form.

Your input

As a start, I submitted a talk proposal to Droidcon NYC. Please fav this tweet if you want to hear it:

However, the talk is only 40-minute long, highlighting maybe a quarter of this outline. It will take a lot more effort to flesh out the whole outline, so please let me know your interest by filling in this form: http://bit.ly/1H0X4up. Thank you!

Update: I have started publishing Espresso courses! https://gumroad.com/chiuki. Still trying to figure out what topics to tackle next, so I'd really appreciate your input.
