When I started http://Fairpixels.pro http://Fairpixels.pro, I did exactly this. Only instead of an email list, I was writing posts on Reddit.

Most of the time, things you may have missed (because they seemed obvious to you). Building in the open seems to be happening more often lately but we need more of that.
