This was your "weekend" project right? I remember seeing it and reading the blog post a while ago. Would you be willing to share some info on your numbers (visits, conversion rates etc)?
I've done little to no marketing for it, most of my customers have come from the press I got for the Highrise integration and the rest came from blog entries here and there.
I did get a ton of customer feedback (some through Survey.io, others from direct customer development) which has lead me to release this updated version.
I'm going to be focusing more on marketing Tout over the next few months.
