Well I'm doing both. Like many of my intended audience, I'm doing it part-time (nights and weekends), while working on Quiver doing during the day. It's progressing quite steadily and over the last 10 years, I have learned to become a lot more efficient with my time. My last startup was also about time management, so I have a lot of experience helping people finish what they start.
I should add that this is really scratching my own itch. I wanted a place where I could learn and build in public, so I decided to create a place like that.
